MRI for oncology -
Ask the care team about any restrictions ahead of test day. If the patient is feeling nervous before the procedure, he or she should ask whether the facility provides ear plugs or headphones during the test.
A patient may be able to use music for support or distraction during the procedure. A patient should have medical records organized. These may include past scans for a comparison to new results , surgeries and a list of current medications.
That includes piercings, and any medical or other implants that contain metals. If a patient has any of these implants, talk to the care team. Tattoos are generally safe for patients having an MRI.
According to the U. Food and Drug Administration , some people may experience mild swelling or burning in the tattoo area, but this is rare and resolves on its own. Patients with severe renal failure who are undergoing dialysis should generally avoid using MRI with contrast. Dialysis patients should only get contrast MRI when essential and undergo dialysis as soon as possible after the scan.
These symptoms may develop slowly over a few weeks to a few months, and may include:. MRI is generally avoided during pregnancy, especially during the first trimester.
No adverse effects have been noted, but the first three months of pregnancy is a sensitive time for the developing fetus. Contrast agents may transfer to the fetus, so they should also be avoided if an MRI is necessary during pregnancy.
Patients who are breastfeeding should inform the technologist before getting an MRI with contrast solution. According to guidelines from the American College of Radiology , breastfeeding is safe after taking the contrast solution, but patients with concerns may opt to wait for 24 hours before breastfeeding again.
Some patients express extra milk and store it before the scan, then express and discard the milk for one day after the scan. The solution is cleared from the bloodstream in 24 hours. Breastfeeding may muddy the MRI image, particularly if there is a breast concern.
If possible, patients wait up to six months after stopping breastfeeding, or use an alternate imaging method to get a clearer picture.
During the MRI, to get the most accurate images, a patient may be asked to lie very still while the designated area of the body is being scanned. The technologist may ask the patient to hold his or her breath at certain times during the scan to create the clearest images.
Patients are encouraged to speak up if they have any trouble during the scan. If a patient is feeling anxious, it may help to lean on a loved one for support.
Check with the facility to see if there are any restrictions on someone coming with the patient. Patients with even mild claustrophobia may experience anxiety during an MRI. The process may take up to two hours, and the patient needs to lie still in a small tube in the machine.
Techniques like visualization or listening to music may help, as well as medical sedation or anesthesia. As a result, a patient may need to repeat the test in a closed-tube MRI to obtain a clearer image.
The MRI process itself is painless. A patient may feel a slight twitching sensation during the test or warmth in the scanned area. The noise may be intense and uncomfortable.
If a patient receives contrast with their MRI, an IV or injection may be needed, which may pinch or cause pain. After the MRI, patients should check in with their doctor about the results. There are typically no side effects or restrictions after an MRI.

A strategy of foregoing biopsy among males with low-suspicion MRIs scores equivalent to prostate imaging reporting and data system [PI-RADS] 1 and 2 see 'Prostate imaging reporting and data system PI-RADS ' above might have avoided a biopsy in 27 percent of males and would have missed only 5 percent of the clinically significant cancers.
The authors concluded that TRUS biopsy performs poorly as a diagnostic test for clinically significant prostate cancer, that MRI used as a "triage" test before first prostate biopsy could identify one-quarter of males who might safely avoid biopsy, and that it might improve the detection of clinically significant cancer.
However, this is not yet a standard approach at most institutions. See 'Do males with a negative MRI need TRUS biopsy? Importantly, due to the era of the study's conception, the MRI studies were performed on a lower field strength magnet than is used in many centers today, and it employed a five-level Likert reporting system rather than the modern PI-RADS version 2 PI-RADS v2 rubric.
See 'Prostate imaging reporting and data system PI-RADS ' above. Among these diagnostic strategies, the MRI pathway had the most favorable diagnostic accuracy for the detection of clinically significant prostate cancer the primary target condition was defined as International Society of Urological Pathology [ISUP] grade 2 or higher prostate cancer table 1 in biopsy-naïve males or those with a prior negative biopsy.
Assuming a baseline cancer prevalence of 30 percent, this would result in true positives, 28 false positives, true negatives, and 84 false negatives per men. Again, assuming a baseline cancer prevalence of 30 percent, this would result in true positives, 0 false positives, true negatives, and false negatives per men.
The MRI pathway still missed some males with important prostate cancers. The following conclusions were drawn:. One trial showed a decrease in pain and bleeding adverse effects with MRI and targeted biopsy [ 13 ].
Most of these were classified as clinically insignificant, and the risk of a patient having a clinically significant prostate cancer and negative MRI findings ranged between 0 and 23 percent. Limitations of this analysis were that two of the trials did not use identical biopsy approaches for all patients in both study groups, variability in the definition of clinically insignificant prostate cancer in all of the trials, and the fact that test properties such as sensitivity and specificity could not be calculated because most patients did not undergo a reference standard procedure ie, saturation biopsies using a template or prostatectomy.
On the other hand, four other prospective analyses not included in the meta-analysis suggest that the information obtained from MRI is complementary to systematic TRUS-guided biopsies, and that the greatest sensitivity for detecting clinically significant disease is achieved by combining the two methods [ ].
Thus, taken together, the available evidence suggests that incorporation of prebiopsy MRI should be recommended for diagnostic pathways for males referred for biopsy because of suspected prostate cancer.
However, widespread acceptance of prostate MRI for all males prior to planned biopsy has been limited by significant problems with technical and clinical expertise, leading to one single-institution study reporting subjective and inconsistent interpretation of multiparametric MRI on a per-lesion basis, with false positives particularly in the transition zone and false negatives particularly for smaller non-index lesions [ 61 ].
In addition, several blood markers are now available that can help to predict the risk of high-grade cancer in males with an elevated PSA level, including the free PSA ratio, the PHI, and the 4K score.
Since there are no studies comparing any of these tests with prostate MRI, the appropriate sequence of testing prior to prostate biopsy has yet to be determined [ 62,63 ]. There have been concerns about the financial cost of MRI, and the economic implications of widespread policies recommending prostate MRI for all males with clinical suspicion for prostate cancer remain unclear.
However, multiple studies appear to demonstrate that incorporating prebiopsy MRI into the diagnostic pathway for males referred for biopsy because of clinical suspicion of prostate cancer is cost effective despite the initial expense of MRI because the cost of the MRI is offset by the avoidance of unnecessary biopsies, a decreased detection of clinically insignificant tumors, and a refined estimate of risk, including identifying males with low- and very low-risk disease who might be suitable candidates for active surveillance [ ].
Notably, these findings are sensitive to test cost, the sensitivity of MRI-targeted biopsy, and the long-term outcomes of males with cancer. See 'Males choosing active surveillance' below.
The issue of whether males with a negative MRI can forego systematic biopsy is addressed below. Can any test predict who might benefit from prebiopsy MRI?
A later analysis of this cohort suggested that the fraction of documented cancer cases that were upgraded to clinically significant disease based on MRI versus TRUS was higher in males with initially higher PSA levels [ 69 ].
The authors concluded that using a threshold PSA level of 5. Below this value, core TRUS-guided biopsy detected more clinically insignificant cancers.
In a smaller subset of males with no prior biopsy, a cutoff of 6. However, in our view, these data are insufficient to conclude that any magnitude of PSA elevation can be used to select males for initial MRI.
Should males with positive MRI scans only undergo targeted biopsy? This is particularly true when the patient is biopsy naïve. While it has been suggested that MRI-positive patients undergo only MRI-targeted biopsy, with no accompanying systematic biopsies [ 13,28,71 ], this position is countered by the consistent literature finding of higher grade disease not being detected on MRI-directed biopsy cores but on accompanying TRUS biopsy cores in up to 21 percent of cases , which might have led to undertreatment due to risk misclassification if the TRUS biopsy were eliminated [ 23,33,39,57,58,60, ].
As an example, in one prospective trial, omitting systematic biopsy halved the probability of detecting clinically insignificant prostate cancer, but one in five clinically significant cancers were missed [ 75 ].
Furthermore, several prospective analyses suggest that the information obtained from MRI is complementary to TRUS-guided biopsies, and that the greatest sensitivity for detecting clinically significant disease is achieved by combining the two methods [ ,76 ]. As examples see "Prostate biopsy", section on 'Targeted biopsy' :.
Targeted biopsies had higher cancer detection rates per core than systematic biopsy 38 percent software versus 33 percent cognitive versus The overall cancer detection rate was greatest 70 percent when systematic and targeted results were combined, as the discordance of tumor locations suggested that the different biopsy methods detect different tumors.
Overall, 21 percent had a tumor detected by systematic biopsy that was missed by MRI-targeted biopsy, while 10 percent had a tumor detected by targeted biopsy that was missed by systematic biopsy.
Combined biopsy detected more cancers than either method alone The corresponding rates for upgrades to grade group 2 or higher disease were 6. Do males with a negative MRI need TRUS biopsy? While several studies [ 13,28,78 ] have proposed that males with an elevated PSA or abnormal DRE who have negative multiparametric prostate MRI studies ie, PI-RADS 1 or 2 may forego prostate biopsy largely based on the high sensitivity and NPV [between 63 and percent] of prostate MRI [ 28, ] , there are few prospective data addressing the validity of this approach, and it is not currently recognized by the AUA or the NCCN [ 48 ] clinical guidelines for routine practice.
While fewer clinically insignificant cancers were found in the MRI-targeted biopsy group 12 versus 4 percent , the number of clinically significant cancers was similar 21 versus 18 percent, difference 3 percent, range -1 to 7 percent , and the use of an MRI-based biopsy strategy was deemed noninferior to the standard strategy.
Given that the detection rate in the experimental group was no lower than in the control group, the false negative rate of the experimental group might be comparable with the control group.
However, without a gold standard eg, saturation biopsies, as have been done in other studies , the true numbers of clinically significant cancers that were missed because of the negative MRI is not clear. Some authors suggest that this approach be limited to those with a lack of high-risk features eg, clinical suspicion, family history, low PSA density [ 26,60 ] , and that low scores on the 4K, PHI, or prostate cancer antigen 3 gene PCA3 assays [ 84 ] might give some confidence that a biopsy is not needed.
Use of these assays is discussed in detail elsewhere. See "Measurement of prostate-specific antigen", section on 'Advances in PSA testing'. Staging — Prostate MRI may aid in the staging evaluation by verifying organ-confined status and thus supporting the decision to perform nerve-sparing radical prostatectomy , evaluating the status of the pelvic lymph nodes, and establishing the location and local extent of the tumor in patients being considered for radiation therapy.
Multiparametric prostate MRI using a 3 T magnet is useful for predicting extraprostatic extension at surgery [ 85 ]. It is often used for surgical planning, specifically to define the relationship of the tumor to the neurovascular bundle and to determine the need or risk of sacrificing the nerves either unilaterally or bilaterally.
There is good evidence that prostate MRI prior to radical prostatectomy can be used to verify organ-confined status and thus support the decision to perform nerve-sparing radical prostatectomy [ 86 ].
However, this practice has not been incorporated as a standard of care in major practice guidelines. See "Initial staging and evaluation of males with newly diagnosed prostate cancer", section on 'Evaluating the extent of local disease'.
Staging MRI examinations are also used in planning radiation treatments external beam or brachytherapy ; the MRI can provide location information and estimates of tumor volume for dose planning. The role of MRI for the assessment of pelvic lymph node status has also been evaluated, and it appears to match or outperform computed tomography CT [ 87 ].
Males choosing active surveillance — MRI of the prostate is often obtained in males with very low- and low-risk disease table 3 who are considering active surveillance to ensure that high-grade disease has not been missed. There is also the potential for MRI examinations to augment and replace some of the follow-up biopsies, although prospective data to support this strategy are not yet available.
Guidelines from expert groups on this point are variable. Insurance coverage for prostate MRI is not universal, and this may limit access to patients who are biopsy naïve.
For males with very low- or low-risk prostate cancer table 3 , management with active surveillance has demonstrated favorable long-term treatment-free and oncologic outcomes in appropriately selected patients [ 88 ].
See "Active surveillance for males with clinically localized prostate cancer". There is no consensus on the optimal way to select males for active surveillance.
In our view, and that of others, MRI of the prostate has become an important component of optimizing patient selection for active surveillance. The strength of MRI in this setting comes from its high NPV between 68 and percent [ ] for clinically significant disease.
A negative MRI also provides reassurance to patients that their disease is truly low risk, and thus, it may improve retention in an active surveillance approach. The view that prostate MRI may aid in the identification of occult higher grade tumors, even among patients with known clinically low-risk disease, is supported by the following studies:.
The data are less robust on whether MRI is beneficial as a monitoring tool for males undergoing active surveillance, and it remains uncertain whether the addition of MRI will add value to systematic biopsy and clinical variables in longitudinal follow-up.
This subject is covered in more detail elsewhere. See "Active surveillance for males with clinically localized prostate cancer", section on 'Monitoring and triggers for intervention with treatment'. Another option in this setting to identify males at a higher risk of pathology upgrade at the time of radical prostatectomy is use of one of several validated tissue-based genomic assays eg, the Oncotype DX Genomic Prostate Score, Prolaris, Decipher.
Guidelines from the NCCN and ASCO both support use of these molecular assays to improve risk stratification in males considering active surveillance who have low-risk or favorable intermediate-risk disease if the results of the assay, in conjunction with standard clinical parameters, might change clinical management eg, males considering active surveillance for low-risk or favorable-risk intermediate-grade disease [ 97,98 ].
Some examples include high-volume Grade Group 1 disease, Grade Group 1 disease with abnormal DRE or high PSA density, or low-volume Grade Group 2 disease table 1. The ASCO guideline also addressed the relative value of prostate MRI and tissue biomarkers in this setting, concluding that each of these approaches can provide clinically relevant information regarding the likelihood of upgrading on subsequent biopsy or prostatectomy, there are few studies directly comparing MRI versus genomics in this setting [ 99, ].
Although there are patients for whom both MRI and biomarker testing can provide independent information, the increased testing intensity would clearly increase cost, and it is not clear which specific patients may benefit from both.
See "Molecular prognostic tests for prostate cancer", section on 'Clinical utility and guidelines from expert groups' and "Active surveillance for males with clinically localized prostate cancer", section on 'Tools to refine the selection of males for AS'.
Suspected local recurrence after prostate radiation therapy — For males with biochemical failure following radiation therapy for clinically localized prostate cancer who have undergone a negative prostate biopsy, multiparametric MRI may be helpful in differentiating between residual local disease and distant metastatic spread.
In addition, for those being considered for salvage prostatectomy, MRI has been used to identify seminal vesicle invasion or extraprostatic extension features that identify males who are unlikely to achieve long-term disease control.
See "Rising serum PSA following local therapy for prostate cancer: Diagnostic evaluation" and "Rising serum PSA after radiation therapy for localized prostate cancer: Salvage local therapy". Studies of MRI following prostate radiation therapy appear to offer benefit in the setting of suspected clinical local recurrence based on rising PSA [ , ].
In the absence of clinical suspicion for disease recurrence, however, MRI is not indicated to assess treatment response. MRI is helpful in males postprostatectomy with biochemical failures, allowing for detection of recurrent or residual disease in the resection bed. This information defines the local tumor recurrence and allows for careful planning and delivery of salvage radiation therapy or focal, image-guided, ablative salvage therapy, such as cryotherapy.
Multiparametric MRI may also be helpful in differentiating between residual local disease and distant metastatic spread. See "Rising serum PSA following local therapy for prostate cancer: Diagnostic evaluation".
Males considering focal therapy — Ablative technologies that render treatment to a portion of the prostate believed to be a dominant focus of cancer have been limited in their ability to reliably locate and monitor effect.
MRI can precisely locate an index lesion to provide guidance in focal image-guided therapy treatments. The integration of MRI guidance offers a promising means by which to direct therapies, including high-intensity focused ultrasound, cryotherapy, brachytherapy, or photodynamic therapy, although this application has not yet been evaluated in a prospective manner with longitudinal follow-up.
There is consensus that multiparametric MRI will guide these therapies and posttreatment follow-up in combination with PSA [ ]. See "Cryotherapy and other ablative techniques for the initial treatment of prostate cancer".
METHODS FOR MRI-TARGETED PROSTATE BIOPSY — Directed biopsy targeting prostatic magnetic resonance imaging MRI lesions increases the yield and detection rate of clinically significant, high-grade prostate cancer.
The location and size of suspicious focal lesions can help in determining the need for transperineal or transrectal approaches to the diagnostic biopsy, along with cognitive, fusion, or gantry image guidance.
All of these approaches have demonstrated comparable tumor detection rates [ , ], but they are all associated with technical challenges, require some training particularly for urologists, who have less proficiency in MRI interpretation than do interventional radiologists [ ] , and may require a greater time commitment during early adoption.
Transperineal approaches to MRI-directed biopsies have the advantage of avoiding the rectal wall and of reduced rates of postbiopsy infections [ 39, ].
See 'Elevated serum PSA with a prior negative TRUS biopsy' above. At some institutions, including those of most of the authors and editors of this topic, all males who have access to it undergo prostate MRI prior to planned systematic biopsy.
However, there is no consensus on the appropriate selection of males for prebiopsy MRI, and this is an area in evolution. Not surprisingly, guidelines from expert groups are variable. See 'Initial presentation with no prior biopsy' above.
Most biopsy-naïve males with a positive MRI scan who undergo MRI-directed biopsy should undergo systematic biopsy as well. There is no consensus on which patients with a negative prostate MRI can forego biopsy, and at most institutions, especially those in the United States, males with an elevated prostate-specific antigen PSA and a negative MRI are still referred for systematic TRUS-guided biopsy.

Skip to main content. Home About cancer Tests and scans MRI scan. MRI magnetic resonance imaging is a type of scan that uses magnetism and radio waves to take pictures of inside the body.
The scan takes between 15 and 90 minutes. You might have one to find out whether you have cancer and if you do to measure how big it is and whether it has spread. You might also have one to see how well treatment is working. It is a safe test. If you have an injection of contrast dye it can cause a headache, dizziness or a warm flushed feeling.

| Access this article | MRI scanners play an important role in diagnosing cancer , as well as staging and treatment planning. The detailed images from an MRI machine may be able to be used to distinguish between normal tissue and abnormalities.. This helps the radiology team precisely pinpoint how cancerous cells have grown within the body. It also may be useful for revealing metastases , when cancer has spread to a new part of the body. MRI provides greater contrast in the soft tissues of the body than a computed tomography CT scan. As a result, radiologists often use the machine for medical imaging involving the brain, spinal cord, muscle, ligaments, blood vessels and the inside of bones. Specialized MRI machines include functional MRI fMRI scanners, which evaluate blood flow in the brain, and open MRI scanners, which can be used for patients with claustrophobia. During an MRI, positively charged particles called protons in the body line up with the magnets of the MRI. The machine then sends pulses of energy called radio waves, which push the protons out of alignment with the magnetic field. When the radio waves are turned off, the protons realign, releasing energy. MRIs work by detecting this energy and turning it into images. The amount of energy the protons release and how long it takes them to release it depends on their local environment. This difference in energy release is how the machine may distinguish between different types of tissues. Unlike X-rays and CT scans, an MRI does not use ionizing radiation. Ionizing radiation may damage the genetic material in cells, potentially leading to health issues and increasing cancer risk if the dose is high or frequent. Instead, MRI uses a strong magnetic field and radio waves. Because of the large magnets, MRI is not recommended for women in the first trimester of pregnancy or for patients who have electronic devices or metal objects in their bodies, such as bullet fragments, shrapnel, cochlear implants, most pacemakers and defibrillators. An MRI may be performed with or without the addition of contrast agents. These chemicals are swallowed or given through a vein before or during the MRI. They often contain the element gadolinium. Sometimes, doctors may be able to tell if a tumor is cancerous or not based on how it looks on an MRI, but images obtained by an MRI may not definitively diagnose cancer. However, MRI images are an important part of the diagnostic process. MRIs are often used to look for signs that cancer has spread to other body parts. They help the care team identify tumors and monitor their growth over time. The images may also help with treatment planning or show how well treatments are working. An MRI may show abnormalities in these types of soft tissues, which makes the scan successful for locating tumors and other abnormalities. Magnetic resonance imaging is a noninvasive procedure that produces three-dimensional 3D anatomical images of body parts—for a deeper look than with a standard X-ray. Before going in for an MRI, a patient should block out enough time on test day. The procedure typically takes 45 minutes to 60 minutes, but it may take up to two hours. Wearing loose, comfortable clothing may be helpful. Before the MRI, the patient will likely have to change into a medical gown. A change in diet may be necessary before the procedure. Ask the care team about any restrictions ahead of test day. If the patient is feeling nervous before the procedure, he or she should ask whether the facility provides ear plugs or headphones during the test. A patient may be able to use music for support or distraction during the procedure. A patient should have medical records organized. These may include past scans for a comparison to new results , surgeries and a list of current medications. That includes piercings, and any medical or other implants that contain metals. If a patient has any of these implants, talk to the care team. Tattoos are generally safe for patients having an MRI. You will need to remove any clothing that includes metal and could affect the scan. This includes belts, earrings, shirts with snaps or zippers, and glasses. You may be required to remove all of your clothing, as some undergarments may not be compatible with the MRI. You will also need to remove any jewelry you are wearing before the exam, so you may choose to leave that at home. If your clothing cannot be worn during the scan, you can wear a hospital gown. Personal medical history or concerns. Be ready to talk about these topics with your health care team:. Any metal implants or metal fragments in your body. These can cause serious and even life-threatening problems if exposed to the strong magnetic pull of the MRI. For example, people with a pacemaker cannot have an MRI. Insurance, costs, and consent. If you are concerned about the cost of your MRI, find out beforehand what your insurance provider will cover. Ask how much of the cost you will have to pay. Once you get to the doctor's office or hospital, the staff will ask you to sign a consent form. This form states that you understand the benefits and risks of the scan and agree to have it. A health care team member will explain the test before you sign the form, and you can ask any questions that you might have. What to bring. Consider asking if you can bring music to your appointment. Some imaging centers let you listen to music through headphones during the MRI. It may help distract you from the loud noises the MRI machine makes. Before the MRI starts, you will remove jewelry and other metal objects. You may also need to change into a hospital gown. You may need to receive a special dye called a contrast medium before the test. This dye travels through your bloodstream and creates clearer pictures of specific body parts. The contrast dye is given through an intravenous IV line. When the dye is injected into the line, you may feel a cold sensation spreading through your body. You may also get a metallic taste in your mouth, a mild headache, or an upset stomach. These effects typically only last a few moments. Then, you will lie on a movable exam table outside of the MRI machine. You will lie on your back with your arms at your side. Your head will be on a headrest. The technologist may then place small devices, called coils, over or around part of your body. The coils help send and receive radio waves to create a clearer picture. Before the scan begins, the technologist will leave the exam room. They will be in a nearby control room and they will be able to see you through a window or by video. You will also be able to talk with them through an intercom system. Radiologists can review multiple, sequenced cross-section MRI images from many angles: head-on, lateral, and top-to-bottom. Magnetic resonance images can also show if a cancerous tumor has metastasized spread from its initial location to other parts of your body. Those images will display any tumors or abnormalities in bone and soft tissue structures. An abnormal lump or group of cells is called a neoplasm or tumor. A malignant tumor is cancerous — its cells are abnormal and grow uncontrollably. However, not all tumors are cancer. Instead, they may crowd the surrounding tissues or press on nerves or blood vessels. These tumors tend to have clear boundaries, and they do not secrete hormones. If pressure from a benign tumor causes damage or impairment to nearby tissue structures, it may need to be removed. However, if it does return, it ordinarily recurs in the same place. They look and behave differently from normal cells. Cancer cells metastasize. Again, this means that they move into the bloodstream or travel via the lymphatic system to other sites in your body. Once cancer cells reach another location, a malignant tumor will form there. Benign and malignant tumors are generally visible on an MRI. There are a few exceptions to what can be seen, such as growth rates, but the differences between them are typically consistent. MRI scans can help medical professionals detect cancer. And whole-body magnetic resonance imaging WB-MRI has become available to the general public to screen for potential cancer. Oncologists use whole-body MRI more often to manage treatment for patients whose cancer is likely to metastasize to bone marrow, such as prostate and breast cancers. Oncologists and radiologists also use WB-MRI in lymphoma follow-up because of its superior diagnostics compared to positron emission tomography. After learning that MRI can help detect cancer, many people choose to self-refer for MRI scanning as a measure of prevention and control over their health care. Thinking about the possibility of having cancer is terrifying, but scheduling a full-body scan can help set your mind at ease. Your doctor may also refer you for an MRI scan. Typically, a certified radiology technologist conducts your MRI. A radiologist or clinician will review the images and write a report for you or your doctor.

This helps make the experience less intimidating. At ezra, our full-body scans do not use contrast, and your screening — which screens for abnormalities in up to 13 organs — will take less than an hour. If you have any implants, medical devices, or any other permanent metal objects in your body, you should speak to your clinician before scheduling an MRI. If your doctor, radiologist, or technologist clears you anyway, you can proceed with MRI scanning. MRI scans are useful tools for screening many tissues and organs, including the breast, brain, prostate, and spinal cord. The detailed pictures an MRI produces are more precise and more accurate images than X-rays and CT scans make. Not all tumors are cancerous. Reach out today to book your screening online. How It Works. Know Your Risk. Sign In. February 13, Early Detection. Lynette Garet. Unlike CT and positron emission tomography PET scans, MRI scanners do not use ionizing radiation. Whole-body MRI is used as a general screening tool, as well as for assessing bone metastases from breast and prostate cancer. The chances of survival depend on a few factors: The kind of cancer Staging how advanced the cancer is and if it has spread Your age The timing of your cancer detection the earlier your cancer is discovered, the easier it is to treat The reason for this is that, with early detection, treatment options may be less complex, the cost of treatment is often lower, and there may be a significant reduction in the time it takes for the patient to get the care they need.

Staging MRI examinations are also used in planning radiation treatments external beam or brachytherapy ; the MRI can provide location information and estimates of tumor volume for dose planning. The role of MRI for the assessment of pelvic lymph node status has also been evaluated, and it appears to match or outperform computed tomography CT [ 87 ]. Males choosing active surveillance — MRI of the prostate is often obtained in males with very low- and low-risk disease table 3 who are considering active surveillance to ensure that high-grade disease has not been missed. There is also the potential for MRI examinations to augment and replace some of the follow-up biopsies, although prospective data to support this strategy are not yet available. Guidelines from expert groups on this point are variable. Insurance coverage for prostate MRI is not universal, and this may limit access to patients who are biopsy naïve. For males with very low- or low-risk prostate cancer table 3 , management with active surveillance has demonstrated favorable long-term treatment-free and oncologic outcomes in appropriately selected patients [ 88 ]. See "Active surveillance for males with clinically localized prostate cancer". There is no consensus on the optimal way to select males for active surveillance. In our view, and that of others, MRI of the prostate has become an important component of optimizing patient selection for active surveillance. The strength of MRI in this setting comes from its high NPV between 68 and percent [ ] for clinically significant disease. A negative MRI also provides reassurance to patients that their disease is truly low risk, and thus, it may improve retention in an active surveillance approach. The view that prostate MRI may aid in the identification of occult higher grade tumors, even among patients with known clinically low-risk disease, is supported by the following studies:. The data are less robust on whether MRI is beneficial as a monitoring tool for males undergoing active surveillance, and it remains uncertain whether the addition of MRI will add value to systematic biopsy and clinical variables in longitudinal follow-up. This subject is covered in more detail elsewhere. See "Active surveillance for males with clinically localized prostate cancer", section on 'Monitoring and triggers for intervention with treatment'. Another option in this setting to identify males at a higher risk of pathology upgrade at the time of radical prostatectomy is use of one of several validated tissue-based genomic assays eg, the Oncotype DX Genomic Prostate Score, Prolaris, Decipher. Guidelines from the NCCN and ASCO both support use of these molecular assays to improve risk stratification in males considering active surveillance who have low-risk or favorable intermediate-risk disease if the results of the assay, in conjunction with standard clinical parameters, might change clinical management eg, males considering active surveillance for low-risk or favorable-risk intermediate-grade disease [ 97,98 ]. Some examples include high-volume Grade Group 1 disease, Grade Group 1 disease with abnormal DRE or high PSA density, or low-volume Grade Group 2 disease table 1. The ASCO guideline also addressed the relative value of prostate MRI and tissue biomarkers in this setting, concluding that each of these approaches can provide clinically relevant information regarding the likelihood of upgrading on subsequent biopsy or prostatectomy, there are few studies directly comparing MRI versus genomics in this setting [ 99, ]. Although there are patients for whom both MRI and biomarker testing can provide independent information, the increased testing intensity would clearly increase cost, and it is not clear which specific patients may benefit from both. See "Molecular prognostic tests for prostate cancer", section on 'Clinical utility and guidelines from expert groups' and "Active surveillance for males with clinically localized prostate cancer", section on 'Tools to refine the selection of males for AS'. Suspected local recurrence after prostate radiation therapy — For males with biochemical failure following radiation therapy for clinically localized prostate cancer who have undergone a negative prostate biopsy, multiparametric MRI may be helpful in differentiating between residual local disease and distant metastatic spread. In addition, for those being considered for salvage prostatectomy, MRI has been used to identify seminal vesicle invasion or extraprostatic extension features that identify males who are unlikely to achieve long-term disease control. See "Rising serum PSA following local therapy for prostate cancer: Diagnostic evaluation" and "Rising serum PSA after radiation therapy for localized prostate cancer: Salvage local therapy". Studies of MRI following prostate radiation therapy appear to offer benefit in the setting of suspected clinical local recurrence based on rising PSA [ , ]. In the absence of clinical suspicion for disease recurrence, however, MRI is not indicated to assess treatment response. MRI is helpful in males postprostatectomy with biochemical failures, allowing for detection of recurrent or residual disease in the resection bed. This information defines the local tumor recurrence and allows for careful planning and delivery of salvage radiation therapy or focal, image-guided, ablative salvage therapy, such as cryotherapy. Multiparametric MRI may also be helpful in differentiating between residual local disease and distant metastatic spread. See "Rising serum PSA following local therapy for prostate cancer: Diagnostic evaluation". Males considering focal therapy — Ablative technologies that render treatment to a portion of the prostate believed to be a dominant focus of cancer have been limited in their ability to reliably locate and monitor effect. MRI can precisely locate an index lesion to provide guidance in focal image-guided therapy treatments. The integration of MRI guidance offers a promising means by which to direct therapies, including high-intensity focused ultrasound, cryotherapy, brachytherapy, or photodynamic therapy, although this application has not yet been evaluated in a prospective manner with longitudinal follow-up. There is consensus that multiparametric MRI will guide these therapies and posttreatment follow-up in combination with PSA [ ]. See "Cryotherapy and other ablative techniques for the initial treatment of prostate cancer". METHODS FOR MRI-TARGETED PROSTATE BIOPSY — Directed biopsy targeting prostatic magnetic resonance imaging MRI lesions increases the yield and detection rate of clinically significant, high-grade prostate cancer. The location and size of suspicious focal lesions can help in determining the need for transperineal or transrectal approaches to the diagnostic biopsy, along with cognitive, fusion, or gantry image guidance. All of these approaches have demonstrated comparable tumor detection rates [ , ], but they are all associated with technical challenges, require some training particularly for urologists, who have less proficiency in MRI interpretation than do interventional radiologists [ ] , and may require a greater time commitment during early adoption. Transperineal approaches to MRI-directed biopsies have the advantage of avoiding the rectal wall and of reduced rates of postbiopsy infections [ 39, ]. See 'Elevated serum PSA with a prior negative TRUS biopsy' above. At some institutions, including those of most of the authors and editors of this topic, all males who have access to it undergo prostate MRI prior to planned systematic biopsy. However, there is no consensus on the appropriate selection of males for prebiopsy MRI, and this is an area in evolution. Not surprisingly, guidelines from expert groups are variable. See 'Initial presentation with no prior biopsy' above. Most biopsy-naïve males with a positive MRI scan who undergo MRI-directed biopsy should undergo systematic biopsy as well. There is no consensus on which patients with a negative prostate MRI can forego biopsy, and at most institutions, especially those in the United States, males with an elevated prostate-specific antigen PSA and a negative MRI are still referred for systematic TRUS-guided biopsy. See 'Staging' above. See 'Males choosing active surveillance' above. See 'Suspected local recurrence after prostate radiation therapy' above.
