What Should You Know About MRI Scan Service?

The service usually includes a referral or clinical request, a safety questionnaire, preparation instructions, image-taking, and a report sent to the clinician who requested the scan. The scanner may examine the brain, spine, joints, or organs, depending on the clinical question.

MRI can distinguish many soft tissues and can help clinicians assess the size, position, and appearance of an abnormal area. It may support diagnosis, treatment planning, or monitoring, but an image alone does not establish cancer. A radiologist interprets the images alongside your symptoms, examination, and other tests.

Some examinations use contrast material through a vein to make selected tissues easier to see. Tell the imaging team about kidney problems, previous reactions to contrast, pregnancy, implanted devices, metal fragments, or medication patches before the appointment. You will be asked to remove metal objects and may hear loud knocking during the scan.

Follow the centre's instructions about eating, drinking, medicines, and clothing. Ask whether you need someone to accompany you if you have claustrophobia or may receive a medicine to help you relax; you should not drive after sedation unless the clinical team says it is appropriate.

During the scan, staying still helps prevent blurred images. You can usually speak with the technologist through an intercom and may receive an alarm button. If you feel distressed, tell the team; they can pause when clinically appropriate. Learn more about the equipment in [MRI Scanner](/technology/mri-scanner/).

Contact the imaging service promptly if you cannot attend, develop a new illness that affects preparation, or remember a safety detail that was missed during booking. After contrast or sedation, seek urgent medical help for trouble breathing, swelling of the face or throat, fainting, or rapidly worsening symptoms.

For sudden weakness on one side, new difficulty speaking, a seizure, severe sudden headache, or a sudden change in vision, seek emergency care rather than waiting for a routine scan. An MRI may be used when investigating conditions such as a [Brain Tumour](/conditions/brain-tumour/), but symptoms need timely clinical assessment.

Ask what clinical question the MRI is intended to answer, whether contrast is planned, how to prepare, and when and how the report will be discussed. You can also ask whether another test, such as a [Biopsy](/treatments/diagnostics-and-staging/biopsy/), is needed to examine cells when imaging cannot provide a diagnosis.
