What should you know about MRI scan reading?

A radiologist examines the images in several views and considers the body area scanned, the reason for the test, and any earlier images available for comparison. The report may describe normal structures, a finding that needs follow-up, or an appearance that fits with a known condition. Descriptive terms such as size, location, signal, enhancement, or swelling help clinicians communicate what is visible; they do not by themselves give a final diagnosis.

An MRI can help assess a suspected brain tumour, but an image cannot answer every question. A biopsy may be needed when tissue examination is required, while other tests may suit a different concern.

Read the impression section first, then discuss unfamiliar wording with the clinician who requested the scan. Bring the report and images, if available, and mention relevant symptoms, previous treatments, implants, or earlier scans. Ask which findings need action, whether comparison with older images changes the interpretation, and when the next appointment or test should happen.

Seek urgent medical help for new weakness on one side, trouble speaking, a seizure, sudden confusion, severe breathing difficulty, or rapidly worsening symptoms. These warning signs need assessment regardless of whether an MRI report is available. For less urgent concerns, contact the requesting team if the report mentions a new finding and you are unsure how quickly it should be reviewed.

What is the main finding, and where is it located? Which parts are reassuring or uncertain? Do you recommend comparison with earlier images, another scan, or a biopsy? What symptoms should prompt faster contact?
