Every report has the same five parts
Radiology reports follow a near-universal structure. Once you recognise it, a page of dense terminology becomes far more navigable.
- Clinical information. Why the scan was requested. If this does not match your actual problem, tell your doctor — the radiologist answers the question they were asked.
- Technique. Which sequences were run, which body region, whether contrast was given. Dry, but it tells you what was and was not examined.
- Comparison. Whether prior imaging was available. "No prior studies available" is a meaningful limitation — change over time is often more informative than any single scan.
- Findings. The long section. A systematic walk through the anatomy, describing everything, normal and abnormal alike.
- Impression or conclusion. The radiologist's summary of what matters. This is the part your doctor reads first.
Read the impression first
The findings section describes everything the radiologist looked at, which is why it is long and why it can read alarmingly to someone unfamiliar with the format. The impression is where they say what they think it means.
If the impression says the study is normal, the findings section did not contain a hidden catastrophe. It contained a systematic description of normal anatomy, written in technical language because it is addressed to a clinician.
A note on searching your report online
Typing an unfamiliar phrase from a report into a search engine reliably produces the worst possible interpretation, because rare and serious conditions generate far more written content than common harmless ones. The same phrase in context, alongside your history and examination, usually means something entirely ordinary. This is a strong argument for asking your doctor before searching, not after.
The words that sound worse than they are
| Phrase | What it generally means |
|---|---|
| Unremarkable | Normal. The most reassuring word in radiology. |
| No acute abnormality | Nothing needing urgent action was found. |
| Lesion | Simply "an area that differs from its surroundings". Not a synonym for cancer. |
| Degenerative change | Age-related wear. Extremely common and often present in people with no symptoms. |
| Disc bulge | The disc extends slightly beyond its normal margin. Very common; only matters if it compresses something. |
| Signal alteration / hyperintensity | An area behaving differently on a sequence. Meaning depends entirely on where and on which sequence. |
| Oedema | Fluid. Points to inflammation, injury or recent stress. |
| Enhancement | The tissue took up contrast, indicating blood supply or a leaky barrier. |
| Clinical correlation is advised | "This finding only means something alongside the examination." Standard phrasing, not a warning. |
| Cannot be excluded | The scan cannot definitively rule something out. Usually caution, not suspicion. |
The phrase patients most often misread is disc bulge. Imaging studies of people with no back pain at all find disc bulges in a large proportion of them, and the proportion rises steadily with age. A bulge on your report does not, by itself, explain your pain. What matters is whether it corresponds to your symptoms and whether it is compressing a nerve root — which is why the report goes back to your doctor rather than standing alone.
Incidental findings, and why they are so common
An incidental finding is something spotted that had nothing to do with why you were scanned. A small kidney cyst on a spine MRI. A benign liver haemangioma. A thyroid nodule found on a neck study.
They are extremely common, and the more of the body a scan covers, the more of them appear. Most are entirely harmless and need nothing. Some need a single follow-up scan to confirm stability. A few genuinely matter, and finding them early is a real benefit.
The difficulty is that an incidental finding starts a process. A cyst that would never have caused trouble may lead to repeat imaging, sometimes a biopsy, and months of worry. This is the main argument against scanning people who have no symptoms, and it is covered in more detail on our whole body MRI page.
What "unremarkable" actually means
A normal scan does not always mean nothing is wrong. It means nothing was visible on that particular test, of that particular region, on that particular day.
MRI cannot see pain. It cannot see most causes of fibromyalgia, many headaches, early inflammation before structural change, or a condition whose changes are microscopic. A normal MRI in someone with real symptoms is a useful result — it excludes a long list of serious possibilities — but it is not the same as being told there is nothing wrong.
Equally, an abnormal-looking scan in someone with no symptoms frequently needs no action at all.
What to do with the report
- Take it to the doctor who ordered it. They asked a specific question; they are the person who can interpret the answer alongside everything else they know about you.
- Keep the images, not just the report. The CD or digital copy matters. Any future comparison depends on having the earlier images, not merely the earlier wording.
- Write your questions down before the appointment. People consistently forget them once they are in the room.
- Ask what happens next. Treatment, another test, a specialist referral, or watchful waiting — knowing which of the four applies is usually the reassurance people want.
- Do not act on the report alone. Not by starting medication, not by stopping it, and not by booking further scans yourself.
