What should you know about the reason for an MRI scan?

MRI is useful for showing soft tissue, including the brain, spine, joints, pelvis, and many organs. It can help investigate pain, weakness, seizures, bleeding, or a change found on another test. In cancer care, it may help describe a tumour's position, its relationship to nearby structures, and changes during follow-up.

Some scans use a contrast medicine through a vein to make particular tissues easier to distinguish. The radiographer will ask about metal implants, devices, kidney problems, pregnancy, allergies, and previous procedures before scanning. MRI does not use x-rays, but the magnetic field means safety screening is essential.

Follow the appointment instructions about eating, drinking, medicines, and clothing. Remove metal objects and tell the imaging team about implants, shrapnel, hearing devices, or a medication pump before entering the scan room.

During the scan, you lie still on a moving table while the scanner makes loud tapping or knocking sounds. Ear protection is provided, and you can communicate with the team. If enclosed spaces are difficult, discuss support before the appointment; some people need a different plan or medicine to reduce anxiety.

Contact the imaging or referring team before the appointment if you discover a metal implant, develop an illness, or may be pregnant. After contrast, seek urgent help for trouble breathing, facial swelling, fainting, or a rapidly spreading rash. New severe neurological symptoms require emergency assessment rather than waiting for scan results.

What area is being scanned and what question should it answer? Will contrast be used, and do I need kidney-function testing? How long should I allow for the visit? When and how will the result be explained? Do I need another test, such as a biopsy, after the scan?
