Imaging Reports (X-ray, CT, MRI): How to Understand the Language
What is a radiology report, and why does it matter?
A radiology report is the formal written interpretation of an imaging test — X-ray, CT, MRI, or ultrasound — produced by a radiologist (a doctor specialised in reading medical images). It is the primary way that imaging findings are communicated to your referring doctor, and increasingly, patients can access these reports directly through online portals before their next appointment.
This guide is for anyone who has received, or is about to receive, an imaging report and wants to understand how it is structured, what commonly used phrases mean, and which findings typically prompt further action. It applies across imaging types — X-ray, CT, and MRI reports all follow a broadly similar structure, even though the technology behind each is different.
Common misconceptions about imaging reports
- "Any mentioned finding means something is wrong." Radiology reports are thorough by design and often note minor, normal age-related, or incidental findings that require no action.
- "A long report means a serious problem." Report length often reflects complexity of the anatomy being described, not severity of disease.
- "I can fully interpret my own report." Reports are written for other doctors and are best interpreted together with your clinical history by the ordering physician.
- "No news is good news." Always confirm you have received and discussed your result — do not assume a normal result if you haven't heard back.
When to seek medical care about a scan result
Seek urgent care if your report is linked to:
- New severe symptoms (chest pain, breathlessness, sudden weakness) prompting the scan in the first place
- A radiologist's report flagged for immediate physician callback
Book a follow-up appointment promptly if your report includes:
- A recommendation for further imaging or specialist referral
- An unexpected ("incidental") finding requiring monitoring
- Wording such as "correlate clinically" or "follow-up recommended"
Routine follow-up is usually appropriate for:
- Reports stating "no acute findings" with no further recommendations
- Stable findings consistent with previous scans
How imaging reports are usually structured
- Clinical history: why the test was ordered — the symptom or question being investigated
- Technique: how the scan was performed (with or without contrast, which sequences/views)
- Findings: a detailed, structured description of what was seen, organ by organ or region by region
- Impression: the key summary and the radiologist's overall conclusion — usually the most important section for quick understanding

Common terms (plain-English)
| Term | What it usually means |
|---|---|
| No acute findings | Nothing urgent or new identified on this scan |
| Incidental finding | An unexpected finding unrelated to the reason for the scan, often benign |
| Recommend correlation | The radiologist suggests comparing this result with your symptoms, labs, or previous scans |
| Stable | Unchanged compared with a prior scan |
| Cannot exclude | The scan cannot fully rule this out; further testing may be suggested |
X-ray reports have their own terminology — see X-ray report language decoded for common phrases.
Getting the most from a discussion with your doctor
When discussing your report, useful questions include: what does the impression mean in the context of my symptoms, does anything need follow-up imaging or referral, and when should I expect results of any further tests?
