MRI scans
MRI report jargon decoded
A plain-English glossary of the terms that appear in MRI reports - signal change, degenerative, unremarkable, correlate clinically and more.
What to expect
- Preparation: Usually none - eat, drink and take medication as normal unless told otherwise. You will complete a safety questionnaire covering implants and previous surgery, and remove all metal items before the scan.
- During the test: You lie on a motorised couch that moves into the scanner. The machine is noisy, you wear ear protection, and you need to keep as still as possible. Most MRI examinations take 20-45 minutes.
- Results: A consultant radiologist reports the scan, typically within 24-72 hours of your appointment.
- Who follows up: The report goes to your referring GP or specialist, who explains the findings and arranges any follow-up.
- Cost: an indicative cost varies by provider.
About this test
A plain-English glossary of the terms that appear in MRI reports - signal change, degenerative, unremarkable, correlate clinically and more. It is most useful when you have the report in hand before your follow-up appointment.
How to access it privately
You can arrange a private MRI either with a referral from your GP or specialist or, for many scans, by self-referring as a self-pay patient with a short pre-scan questionnaire. Routine NHS diagnostic waits are often long - frequently measured in months - whereas private slots are typically available within days to around two weeks. Costs vary by provider and should be confirmed with the provider before booking.
Frequently asked
Common questions about MRI report jargon decoded.
Quick, plain-English answers to what people ask us most.
-
Why do MRI reports use so much medical jargon?
Radiologists write reports for other doctors, using precise technical language to describe exactly what they see, which is why the wording can feel dense or alarming to a patient reading it directly. Terms like 'hyperintense', 'degenerative change' or 'incidental finding' each have specific meanings that a specialist will interpret in context.
-
What are some of the most common terms, and what do they mean?
'Incidental finding' means something noticed on the scan unrelated to why it was done, which is often harmless. 'Degenerative change' usually refers to common, age-related wear rather than a serious disease, and terms like 'mild', 'moderate' or 'severe' describe the extent of a finding rather than necessarily how much pain or disability it causes.
-
Should I try to interpret my report myself before speaking to a doctor?
It's understandable to want to look up unfamiliar terms, but online searches can make findings sound more serious than they are, since the same wording can apply to both minor and significant issues. It's best to read the report as background and then discuss it properly with the doctor who can put it in context.
-
What happens after I receive my MRI report?
Your referring doctor or specialist will normally go through the findings with you, explaining what the technical terms mean in the context of your symptoms and what, if anything, needs to happen next. Bringing a written list of questions to this appointment can help you get the most out of it.
-
What does it mean if my report mentions something 'not seen elsewhere in this study'?
This kind of phrasing usually means the radiologist looked specifically at that structure and found nothing abnormal, which is a routine and reassuring way of documenting a normal finding. Reports are often written to be systematic and complete, covering areas even when there's nothing of note.
-
How long does it take to get a report explained after the scan?
The radiologist's written report is usually available within a few days privately, but understanding what it means for you comes from the follow-up discussion with your doctor, which is typically arranged soon after. If you're waiting longer than expected for this explanation, it's reasonable to contact the referring clinician's office to check.
-
What do abnormal-sounding terms actually mean for my health?
Many terms that sound alarming, such as 'lesion' (simply meaning an area of abnormal tissue) or 'oedema' (swelling), can refer to entirely benign or treatable findings. The clinical significance always depends on the specific finding, its size, location and your symptoms together, which is why a doctor's interpretation matters more than the words alone.
-
Is there a cost to having my MRI report explained, and is this available on the NHS?
On the NHS, discussing your results is part of your ongoing care through your referring doctor, though appointments can take time to arrange. Some private services offer a dedicated consultation to go through scan results in detail; cost varies by provider.
-
How reliable is it to rely on the written report alone?
The written report is accurate but is written in clinical shorthand for other doctors, so relying on it alone without a follow-up discussion can lead to unnecessary worry or missed context. Reports are most useful when read together with a professional explanation.
-
How can I get help understanding my MRI report privately and quickly?
Many private imaging and specialist clinics offer a follow-up consultation specifically to explain your results in plain language. Contact your imaging provider or a private specialist to check how quickly this can be arranged, often within a few days.
