How to read an MRI report, section by section

Every radiology report follows the same structure. Once you know what each section is for, you can skip straight to the part that answers your question.

Reports are not written for patients, and that is fixable

An MRI report looks like a wall of terminology, and most people read it top to bottom in growing alarm, hitting the worst-sounding word and stopping there.

It is far more navigable than it looks, because radiology reports are not free-form writing. They follow a standard structure, and once you know what each section is for you can go straight to the one that answers your question.

The report was written for the doctor who ordered your scan. Reading it is your right, but nobody adapted it for you. Knowing the shape is what closes that gap.

The sections, in order

The American College of Radiology describes a report as six parts. Most reports you receive have all or most of them:

1. Examination — what was done. "MRI lumbar spine". Sometimes with the date and the equipment.

2. Clinical history / indication — why it was ordered, usually copied from the referral. It is often a single line: low back pain radiating to left leg, 8 weeks. This matters more than it looks: it is all the context the radiologist had about you.

3. Technique — how it was done. Which sequences, whether contrast was injected, how many slices. Almost never relevant to you, and safe to skip.

4. Comparison — whether there were earlier studies to compare with, and which. "No prior studies available" is a common and important line: it means nobody could tell whether a finding is new.

5. Findings — the long section. Raw observations, organ by organ or level by level, with measurements and locations. This is description, not conclusion.

6. Impression — the short section at the end. This is the radiologist's summary and the part your doctor reads first.

Read the impression first

This is the single most useful habit, and it is the opposite of what people do.

The impression distils everything into a few lines: what matters, what it might mean, and what should happen next. The findings section describes everything the radiologist saw, including a great deal that is normal or irrelevant to you.

If you read findings first, you will spend twenty minutes worrying about a phrase that the impression does not even mention — because the radiologist judged it unimportant. Read the impression, then go back into findings for context on whatever it flagged.

A finding that appears in the findings section but not in the impression is usually a finding the radiologist decided was not significant.

Phrases that sound worse than they are

Report language is cautious by profession, and cautious reads as ominous:

  • "Clinical correlation is recommended" — routine. It asks your doctor to interpret the images alongside your symptoms. Explained in full here.
  • "Cannot be excluded" — the images cannot rule it out. Not that it is present.
  • "Nonspecific" — what was seen does not point to a single cause.
  • "Unremarkable" — normal. Genuinely good news, oddly phrased.
  • "No acute findings" — nothing needing urgent attention.
  • "Incidental finding" — something unrelated to why you were scanned. More here.

And the one worth internalising: a description is not a diagnosis. "Disc protrusion at L4-L5" says what a shape looks like. Whether it explains your pain is a separate question, answered by someone who can examine you.

What to take to the appointment

  • The report itself, and your previous ones if you have them.
  • A note of your symptoms — where, since when, better or worse with what. That is the raw material your doctor needs.
  • Your questions, written down. Appointments are short and memory under stress is poor.

Three questions that work for almost any report: Does this explain my symptoms? Is anything here new compared with last time? Does this change what we do?

If you do not have your earlier studies, here is how to request them.

If you would rather not decode it alone

Knowing the structure helps you navigate a report. It does not translate the measurements, the anatomical names, or the finding nobody mentioned to you.

That is what ExplainMyScan does: upload the report, tell us what worries you, and get it back in plain language. It does not diagnose and it does not replace your doctor — it means you walk into the appointment knowing what you are holding.

Frequently asked questions

Which part of an MRI report should I read first?
The impression, at the end. It is the radiologist summary and the part your doctor reads first. The findings section describes everything seen, including a great deal that is normal.
What sections does a radiology report have?
The American College of Radiology describes six: examination, clinical history or indication, technique, comparison, findings, and impression.
What does unremarkable mean in a radiology report?
Normal. It is good news phrased oddly. Similarly, no acute findings means nothing that needs urgent attention.
A finding appears in the findings but not in the impression. Does that matter?
Usually it means the radiologist judged it not significant. The impression is where anything that changes management gets stated.
