MRI for abdominal imaging -

Leave jewelry at home and wear loose, comfortable clothing. You may be asked to wear a gown. If you have claustrophobia or anxiety, you may want to ask your doctor to prescribe a mild sedative before the exam. Magnetic resonance imaging MRI is a noninvasive test doctors use to diagnose medical conditions.

MRI uses a powerful magnetic field, radiofrequency pulses, and a computer to produce detailed pictures of internal body structures. MRI does not use radiation x-rays. You will need to change into a hospital gown. This is to prevent artifacts appearing on the final images and to comply with safety regulations related to the strong magnetic field.

Guidelines about eating and drinking before an MRI vary between specific exams and facilities. Take food and medications as usual unless your doctor tells you otherwise.

Some MRI exams use an injection of contrast material. The doctor may ask if you have asthma or allergies to contrast material, drugs, food, or the environment.

MRI exams commonly use a contrast material called gadolinium. Doctors can use gadolinium in patients who are allergic to iodine contrast.

A patient is much less likely to be allergic to gadolinium than to iodine contrast. However, even if the patient has a known allergy to gadolinium, it may be possible to use it after appropriate pre-medication.

For more information on allergic reactions to gadolinium contrast, please consult the ACR Manual on Contrast Media. Tell the technologist or radiologist if you have any serious health problems or recent surgeries.

Some conditions, such as severe kidney disease, may mean that you cannot safely receive gadolinium. You may need a blood test to confirm your kidneys are functioning normally.

Women should always tell their doctor and technologist if they are pregnant. MRI has been used since the s with no reports of any ill effects on pregnant women or their unborn babies. However, the baby will be in a strong magnetic field. Therefore, pregnant women should not have an MRI in the first trimester unless the benefit of the exam clearly outweighs any potential risks.

Pregnant women should not receive gadolinium contrast unless absolutely necessary. See the MRI Safety During Pregnancy page for more information about pregnancy and MRI. If you have claustrophobia fear of enclosed spaces or anxiety, ask your doctor to prescribe a mild sedative prior to the date of your exam.

Leave all jewelry and other accessories at home or remove them prior to the MRI scan. Metal and electronic items are not allowed in the exam room. They can interfere with the magnetic field of the MRI unit, cause burns, or become harmful projectiles. These items include:. In most cases, an MRI exam is safe for patients with metal implants, except for a few types.

People with the following implants may not be scanned and should not enter the MRI scanning area without first being evaluated for safety:.

Tell the technologist if you have medical or electronic devices in your body. These devices may interfere with the exam or pose a risk. Many implanted devices will have a pamphlet explaining the MRI risks for that device.

If you have the pamphlet, bring it to the attention of the scheduler before the exam. MRI cannot be performed without confirmation and documentation of the type of implant and MRI compatibility.

You should also bring any pamphlet to your exam in case the radiologist or technologist has any questions. If there is any question, an x-ray can detect and identify any metal objects.

Metal objects used in orthopedic surgery generally pose no risk during MRI. However, a recently placed artificial joint may require the use of a different imaging exam. Tell the technologist or radiologist about any shrapnel, bullets, or other metal that may be in your body.

Foreign bodies near and especially lodged in the eyes are very important because they may move or heat up during the scan and cause blindness.

Dyes used in tattoos may contain iron and could heat up during an MRI scan. This is rare. The magnetic field will usually not affect tooth fillings, braces, eyeshadows, and other cosmetics.

However, these items may distort images of the facial area or brain. Tell the radiologist about them. Infants and young children usually require sedation or anesthesia to complete an MRI exam without moving.

Whether your child requires sedation depends on their age, intellectual development and the type of exam. Moderate and conscious sedation can be provided at many facilities.

A doctor or nurse specializing in sedation or anesthesia for children should be available during the exam for your child's safety. You will be given special instructions for how to prepare your child.

Some hospitals employ certified child life specialists to provide children and families with emotional support in medical settings. These specialists have backgrounds in child development, psychology and counseling.

They can prepare children for medical imaging procedures. This can help decrease the child's stress and anxiety and even reduce or eliminate the need for sedation.

Many facilities offer child-friendly imaging suites decorated with murals and lighting that can help entertain and calm pediatric patients. Silent MRI techniques and distraction devices like DVD goggles and music headphones may reduce or eliminate the need for sedation during MRI.

New and improved MRI approaches produce high-quality images and reduce the time children spend in the scanner. This may also eliminate the need for sedation. For more information, see the Pediatric Sedation page. The traditional MRI unit is a large cylinder-shaped tube surrounded by a circular magnet.

You will lie on a table that slides into a tunnel towards the center of the magnet. Some MRI units, called short-bore systems , are designed so that the magnet does not completely surround you. Some newer MRI machines have a larger diameter bore, which can be more comfortable for larger patients or those with claustrophobia.

They are especially helpful for examining larger patients or those with claustrophobia. Open MRI units can provide high quality images for many types of exams. Open MRI may not be used for certain exams. For more information, consult your radiologist. Unlike x-ray and computed tomography CT exams, MRI does not use radiation.

Instead, radio waves re-align hydrogen atoms that naturally exist within the body. This does not cause any chemical changes in the tissues. As the hydrogen atoms return to their usual alignment, they emit different amounts of energy depending on the type of tissue they are in.

The scanner captures this energy and creates a picture using this information. In most MRI units, the magnetic field is produced by passing an electric current through wire coils.

Other coils are inside the machine and, in some cases, are placed around the part of the body being imaged. These coils send and receive radio waves, producing signals that are detected by the machine. The electric current does not come into contact with the patient.

A computer processes the signals and creates a series of images, each of which shows a thin slice of the body. The radiologist can study these images from different angles.

MRI is often able to tell the difference between diseased tissue and normal tissue better than x-ray, CT, and ultrasound. The technologist will position you on the moveable exam table. They may use straps and bolsters to help you stay still and maintain your position.

The technologist may place devices that contain coils capable of sending and receiving radio waves around or next to the area of the body under examination. MRI exams generally include multiple runs sequences , some of which may last several minutes.

Each run will create a different set of noises. If your exam uses a contrast material, a doctor, nurse, or technologist will insert an intravenous catheter IV line into a vein in your hand or arm. They will use this IV to inject the contrast material. You will be placed into the magnet of the MRI unit.

The technologist will perform the exam while working at a computer outside of the room. You will be able to talk to the technologist via an intercom. If your exam uses a contrast material, the technologist will inject it into the intravenous line IV after an initial series of scans.

They will take more images during or following the injection. Some MRI exams, such as MR Enterography, may use oral contrast in order to evaluate diseases of the bowel.

For more information, see the MR Enterography page. When the exam is complete, the technologist may ask you to wait while the radiologist checks the images in case more are needed. The technologist will remove your IV line after the exam is over and place a small dressing over the insertion site.

Depending on the type of exam and the equipment used, the entire exam is usually completed in 30 to 50 minutes. Most MRI exams are painless. However, some patients find it uncomfortable to remain still. Others may feel closed-in claustrophobic while in the MRI scanner.

The scanner can be noisy. It is normal for the area of your body being imaged to feel slightly warm. If it bothers you, tell the radiologist or technologist. It is important that you remain perfectly still while the images are being taken. This is typically only a few seconds to a few minutes at a time.

You will know when images are being recorded because you will hear and feel loud tapping or thumping sounds. The coils that generate the radio waves make these sounds when they are activated.

You will be provided with earplugs or headphones to reduce the noise made by the scanner. You may be able to relax between imaging sequences. However, you will need to keep the same position as much as possible without moving. You will usually be alone in the exam room.

However, the technologist will be able to see, hear, and speak with you at all times using a two-way intercom. Many facilities allow a friend or parent to stay in the room if they have also been screened for safety.

Children will be given appropriately sized earplugs or headphones during the exam. Music may be played through the headphones to help pass the time.
