If your scan report says 'abnormal,' here's exactly what to do next — step by step:
- Don't panic — "Abnormal" covers everything from harmless calcium deposits to findings that genuinely need follow-up. Most are not urgent. Incidental findings are extremely common in modern imaging.
- Read the Impression section first — Scroll to the bottom of your report. That's the radiologist's summary. Everything else is technical description written for clinicians, not for you.
- Write your questions down before seeing your doctor — A patient who arrives with specific questions gets specific answers. A patient who arrives confused leaves confused.
Here's the reality: most people panic after receiving an abnormal scan report because they don't know what they're actually looking at. The report is written for doctors, not for patients. The language is clinical, the phrasing is precise, and nobody calls to explain any of it.
The gap between "report received" and "doctor consulted" is where most of the fear accumulates. That gap is what this guide is built to close — step by step, from the moment the scan report lands to the moment you sit down with your doctor.
Most abnormal scan results are not emergencies. But they do need to be understood correctly.
If you want to understand what a specific finding in your report means before your appointment, FlexReport breaks down the exact language in your report into plain English — findings, location, and the questions to bring to your doctor.

1. What "abnormal" really means ?
Most people read the word "abnormal" and immediately assume the worst. That's a natural response. It's also, in most cases, the wrong one.
Radiologists routinely document even minor findings to avoid missing anything clinically relevant — that's their job. When a report comes back "abnormal," it means one thing: something differs from a textbook-perfect scan image. It doesn't tell you how significant the difference is, whether it's new, or whether it matters to your health at all.
Here's what a single "abnormal" finding can cover:
- A calcium deposit that's been harmlessly sitting in your body for 20 years — extremely common, often never mentioned to the patient until now
Mild disc degeneration in your spine — affects most people over 40, frequently produces no symptoms
A small incidental cyst found during a scan done for something else entirely — usually benign, requires monitoring at most
- Something that genuinely needs follow-up — this exists, but is far less frequent than the three above
The report is not the diagnosis. Your doctor is.
Incidental findings — things spotted by chance during a scan ordered for a different reason — are extremely common in modern imaging. According to RadiologyInfo.org, a significant proportion of routine scans surface findings that require no treatment whatsoever. Your radiologist's job is to notice and record. Your doctor's job is to interpret that finding in the context of your symptoms, your age, and your history.
2. Read the Impression section first — this is where your answer is
Your report has multiple sections. Most people start reading from the top and wade through dense anatomical descriptions before reaching the point. Don't.
Scroll to the bottom. Look for a heading that says Impression, Conclusion, or Summary. That paragraph is the radiologist's actual interpretation — what they concluded after reviewing every image. It's usually a short numbered list. It's what your doctor reads first. Make it yours too.
The language decoder — what each phrase actually signals
The specific words used in the Impression section carry very different urgency levels. This is the table to read before anything else:
| Report language | What it signals | Urgency |
|---|---|---|
| No acute abnormality | Nothing requiring immediate action right now | Not urgent |
| Likely benign | Radiologist leans toward harmless — follow-up may still be advised | Low |
| Clinical correlation advised | Your doctor needs your symptoms and history to interpret this properly | Low–Medium |
| Follow-up in X months | Worth monitoring, not an emergency | Low–Medium |
| Cannot exclude / Rule out | Further testing needed to confirm or dismiss a possibility | Medium |
| Urgent / Immediate / Critical | Call your doctor today — do not wait | Act today |
If your Impression section contains "urgent," "critical," or "immediate," call your doctor's office today. Don't wait for the appointment. For everything else — and this is the vast majority of abnormal scan results — you're looking at a finding that needs clinical context, not emergency action.
One phrase that appears in a large proportion of routine reports and causes disproportionate alarm is "clinical correlation advised." NHS guidance on scan results confirms this is standard clinical language — it simply means the radiologist wants your doctor to review the finding alongside your symptoms and history. Here's exactly what it means and why it's not a red flag.
3. What NOT to do after an abnormal scan report
This section matters as much as the steps above. The mistakes people make in the hours after receiving an abnormal result are predictable — and all of them make things worse.
Don't Google individual terms in isolation
Searching a single word from your Impression section — "lesion," "opacity," "nodule" — without any of the contextual information in your report returns generic results that cover every possible severity level. That's what general medical sites explain. What they can't tell you is what that term means in your scan, at your location, with your characteristics. Your anxious brain will fill that gap with the worst option.
Don't assume worst-case scenarios
The brain under stress has a strong bias toward the most alarming interpretation available. This is a survival mechanism — and it's completely counterproductive when reading a radiology report. The most alarming interpretation is almost never the most likely one. Radiologists document findings conservatively and thoroughly. "Cannot exclude" does not mean "is likely."
"Cannot exclude" is not a diagnosis. It is a thorough radiologist covering every possibility.
Don't skip or cancel your doctor appointment
Physical symptoms improving does not mean the scan finding has resolved. Some findings that need attention produce no noticeable symptoms at all. The appointment is how the clinical picture gets completed. Keep it.
Don't try to interpret the images yourself
Radiology images require years of trained clinical reading. What looks alarming on a scan image to a patient — a shadow, a bright spot, a density — is often a normal anatomical structure seen from an unfamiliar angle. The Impression section is the radiologist's interpretation of those images. Trust their written summary, not your reading of the raw image.
Don't rely on symptoms alone to decide whether to follow up
"I feel fine, so it's probably nothing" is a dangerous shortcut. Feeling physically well and having a scan finding that needs clinical assessment are not mutually exclusive. Your doctor needs to make that call — not your current symptom level.
4. Understand what your report is saying — before you open Google
Here's what almost no one tells you: there are two completely different ways to engage with a radiology report after the Impression section, and only one of them is useful.
The two sections worth reading after the Impression
Technique / Clinical Information (top of the report) — what type of scan was done and what the referring doctor asked the radiologist to look for. This tells you why a finding was flagged. Understanding the clinical question changes how you interpret the answer.
Findings (the main body) — read this after the Impression, not before. You're reading evidence for a conclusion you've already seen. That context makes the technical language significantly less frightening.
The type of scan matters for how to read the Findings section. If your scan was an MRI, this guide walks through an MRI report section by section. If it was a CT scan, see how to read a CT scan report — the structure is different and the terminology differs significantly.
5. What to do before your doctor appointment — use the gap productively
The days between receiving your report and seeing your doctor are where anxiety compounds fastest. Here's how to use that window productively instead of anxiously.
Write down what confused you — specifically
Re-read your Impression section once more. Write down what you think it's telling you and where your understanding breaks down. The goal is not medical accuracy — it's pinpointing what's unclear so you can ask about it directly.
I read the word 'mass' and I don't know what kind of mass this is or whether I should be worried" is a much more productive starting point than "I don't understand any of it.
Write your question list — then bring it
Doctor appointments are short. Without a written list, you'll forget the most important things in the room. These are the questions that count after an abnormal scan result:
- What exactly was found and where is it located?
- Based on my history and symptoms, what does this most likely mean?
- Does this need further investigation? What kind, and how soon?
- What would make this finding more serious — and what would make it less concerning?
- What symptoms should I watch for and act on before our next appointment?
- What is the most likely outcome here?
Two other things to do before the appointment
- Don't cancel if you feel better. Physical symptoms improving doesn't mean the scan finding has resolved. Keep the appointment.
- Bring someone with you. Medical information is harder to absorb under stress. A second pair of ears doubles what you retain from a short consultation.
6. At the appointment: use your report as a tool, not a source of dread
Most patients arrive at a post-scan appointment in receiving mode — there to be told things. That's a passive position. Shift the frame: you're there to have a conversation, and your report is where it starts.
Open with what you understood
Start by telling your doctor what you took from the Impression section. "My understanding is that [X] was found. Is that right?" This lets them immediately correct any misreading and shows you've engaged. Most clinicians respond better to a patient who arrives prepared than to one who arrives cold.
Ask your most important question first
If the appointment runs short — and they do — you want the thing that's been worrying you most on the table before time runs out. Don't save the difficult question for last.
Before you leave: get the next step and the watch list
Always leave with clarity on two things: the next step (follow-up, referral, test, or watch and wait) and what symptoms would change the plan. Without this, the gap between the appointment and what comes next becomes another anxiety window.
7. After the appointment: four outcomes — and only one of them is serious
When your doctor reviews the scan alongside your symptoms, history, and physical examination, most findings resolve into one of four very different paths.
Three of the four outcomes below require no urgent action. One does. Here's how to tell which one you're in.
No further action needed
The doctor reviews the finding with full context and concludes it's benign, incidental, or within normal variation for your age. Ask them to explain the reasoning, not just the conclusion — understanding why something isn't concerning is more durable than just accepting the reassurance.
Watchful waiting — repeat scan in 3 to 12 months
One of the most common outcomes. Low-concern, worth monitoring to confirm nothing changes. Very frequent for thyroid nodules, small lung nodules, liver cysts. Read about tracking radiology findings across multiple scans. Write the follow-up date in your calendar now.
Referral to a specialist
A referral is not a diagnosis. It means someone with deeper expertise in this finding type needs to assess it. Ask which department, the expected wait time, and what to do if new symptoms develop before that appointment.
Further testing — biopsy, additional scan, or blood tests
Some findings need more data before any conclusion is possible. Ask what the test is looking for and what the result timeline looks like. Having that information makes the waiting period significantly easier to manage.
Frequently asked questions
Can an abnormal scan result be nothing?
Yes — and more often than people expect. A large proportion of abnormal findings turn out to be incidental, age-related, or within normal anatomical variation. "Abnormal" means the image differs from textbook-perfect. It doesn't mean something is clinically wrong. Your doctor's assessment of that finding in the context of your health is what determines significance.
Can a radiology report be wrong?
Radiology reporting is a high-skill clinical discipline, and radiologists are specifically trained to read and interpret medical imaging. Like any clinical process, there is a margin of human variability —which is exactly why significant findings are often reviewed by a second radiologist within the reporting centre, and why your referring doctor reviews the report against your clinical picture. If you have concerns about the interpretation of a specific finding, a formal second opinion from another radiologist is a legitimate option and many patients pursue one for peace of mind.
Do radiologists make mistakes?
Radiologists are highly trained specialists, and the miss rate for significant findings in modern radiology is low. That said, radiology interpretation involves clinical judgement, and no diagnostic process is infallible. If you feel a finding hasn't been adequately explained or a concern has been missed, your referring doctor can request a second read, or you can pursue an independent second opinion. The goal of any radiology report is to be thorough and conservative — which is also why reports sometimes flag findings that turn out to be clinically insignificant.
Should I get a second opinion for an abnormal scan?
A second opinion is always a reasonable option, particularly for significant or ambiguous findings, before agreeing to a major intervention like surgery or biopsy. You don't need a "reason" to seek one — it's a normal part of informed patient decision-making. Read when and how to get a second opinion on a radiology report.
How accurate are MRI and CT scan results?
MRI and CT scans are highly sensitive diagnostic tools — meaning they are good at detecting findings that are present. High sensitivity is a feature, not a flaw, but it also means scans sometimes surface findings that turn out to be clinically insignificant under clinical assessment. The accuracy of the scan in detecting a finding is separate from the clinical significance of that finding — and only your doctor can determine the latter. For more detail on how imaging findings are classified and interpreted, RadiologyInfo.org provides a thorough overview of how radiology reports are produced.
How often are abnormal scan results actually serious?
The majority of flagged findings are not serious in the sense that they require urgent intervention. Serious findings requiring immediate action represent a small subset of abnormal results. That said, "serious" depends entirely on the specific finding, its location, your age, and your medical history — which is exactly why your doctor's assessment matters more than the report language alone. If you want to understand what your specific finding typically means for patients, FlexReport explains the exact terms in your report.
Should I worry about an abnormal CT scan result?
CT scans are highly sensitive — they frequently detect minor findings that are clinically insignificant. An abnormal CT result covers a very wide range. Read your Impression section first and note the specific language (the urgency table in Section 2 above is the reference). Most CT abnormalities are not urgent. Bring the report to your doctor with your question list.
What does an abnormal MRI result mean?
An abnormal MRI result means the scan showed something that differs from a baseline-normal image. This covers a very wide range: white matter changes, T2 signal findings, disc bulges, small cysts, and many others — most of which are either benign or require only monitoring. The Impression section of your MRI report summarises what the radiologist concluded. For a full breakdown of what common MRI findings mean for patients, see our guide to reading an MRI report.
What does 'clinical correlation advised' mean?
It means the radiologist wants your referring doctor to assess this finding alongside your symptoms, history, and physical examination — because the scan alone doesn't provide a complete picture. It is not a red flag. It appears in a very large proportion of routine radiology reports. Read the full guide to 'clinical correlation advised'.
How soon should I see my doctor after an abnormal scan?
For most findings described as "mild," "likely benign," or "requires follow-up," seeing your referring doctor within 3-4 days is appropriate. If your report contains "urgent," "critical," or "immediate," call your doctor's office today. If you can't reach them and symptoms are severe, go to an emergency room.
What if my doctor says everything is fine but I'm still worried?
Ask your doctor to walk you through the specific reasoning — not just the conclusion. If you're still not satisfied after that conversation, a second opinion from another clinician is entirely legitimate. Read: when and how to get a second opinion on a radiology report.
