An MRI scan may be recommended when detailed imaging is needed to investigate abdominal, pelvic or soft tissue symptoms. MRI uses strong magnetic fields and radio waves rather than X-rays and may involve the use of contrast dye to show certain tissues, areas of inflammation or blood vessels more clearly. Safety screening is important because some implanted medical devices or metal fragments can affect whether the scan is suitable.

MRI produces detailed cross-sectional images of the body and is particularly useful for examining soft tissues, the brain and spine, joints, the abdomen and pelvis. When investigating abdominal conditions, MRI or magnetic resonance cholangiopancreatography (MRCP) may be used to assess the liver, pancreas, bile ducts and gallbladder region.

Some MRI scans involve an injection of contrast dye to provide clearer images of blood vessels, inflammation or specific tissues. The contrast used for MRI is different from the iodine-based contrast used for some X-rays and CT scans. Before it is administered, the radiology team will ask about any allergies, kidney problems or previous reactions to contrast agents.

As MRI uses a powerful magnet, it is important to tell the radiographer about any pacemakers, defibrillators, aneurysm clips, implanted pumps, cochlear implants, neurostimulators, shrapnel, metal fragments, stents or other metal implants. Many modern implants are compatible with MRI, but their safety must be confirmed before the scan takes place.

Preparation varies depending on the area being examined. Many MRI scans do not require any special preparation, although patients having certain abdominal scans may be asked not to eat or drink for a specified period beforehand. Any instructions provided in the appointment letter should be followed carefully.

During the scan, you will lie on a movable table that slides into the MRI scanner. The machine can be noisy, so ear protection will be provided. It is important to remain still while the images are taken, and during some abdominal scans you may be asked to hold your breath for a few seconds at a time.

Some patients may feel anxious or enclosed inside the scanner. If you have claustrophobia or are concerned about the procedure, you should tell the radiology team before your appointment. They can offer reassurance and support, and sedation may be considered in some circumstances.

If you have not received sedation, you can usually return to your normal activities immediately after the scan. Patients who have been given contrast may be observed briefly before leaving. The images will be reviewed by a radiologist, and the results will be discussed with you by your specialist.

MRI can help investigate unexplained abdominal pain, pancreatic conditions, abnormalities of the bile ducts, liver lesions and other soft tissue concerns. Your surgeon or specialist will advise whether MRI, ultrasound, CT, MRCP, endoscopy or another investigation is the most appropriate next step.
