In plain language
Genuinely undecided. The finding looks like it could go either way and the scan cannot break the tie, so something else — a follow-up, a different scan, a specialist — has to.
Upload your MRI, CT, X-ray or ultrasound — de-identified in your browser — and every finding is mapped onto your images and explained without jargon.
Where you'll see this
The impression, usually alongside a recommendation for the next step.
Your report may word it “Inconclusive” or “Indeterminate”. These mean the same thing.
Questions worth asking your doctor
- Does this wording mean you are unsure, or that you are reasonably confident and being careful?
- If something cannot be ruled out from this scan, what would rule it out?
- Is there anything here you would act on today?
How often does this turn up?
Equivocal means the images can be read more than one way and the radiologist is not able to come down on either side. It sits in the middle of radiology’s confidence scale — below suspicious for and consistent with, above cannot be excluded — and it turns up whenever an appearance sits genuinely on a boundary.
Does it mean something is wrong?
It is neither reassurance nor warning, and reading it as either is a mistake. What it does mean is that the question is still open, which makes it one of the few report words that reliably implies something further will happen. Radiologists use it sparingly, because an equivocal report creates work; when it appears, it is usually because committing either way would have been dishonest.
What to do with it
Something almost always follows, and a good report says what: a different kind of scan, contrast, a repeat at an interval, or a test outside radiology. Time is frequently the resolver, since an appearance that has not changed over months is usually settled by that alone. If your report says equivocal and no plan has been communicated, that is a fair and specific thing to chase — not because it is alarming, but because the word explicitly leaves the question unanswered.
Frequently asked questions
- Is equivocal bad news?
- No — it is the absence of news. The images support more than one interpretation and the radiologist has declined to guess. It says nothing about which way the answer will fall.
- Why can they not just decide?
- Because committing without support would be worse. Imaging shows appearance rather than tissue, and some appearances genuinely sit on a boundary. Saying so is more useful than a confident answer that might be wrong.
- What usually happens next?
- Whatever resolves the ambiguity: another imaging technique, contrast, a follow-up at an interval, or a non-radiological test. Repeat imaging after a defined period is the most common, because change over time settles a great many equivocal findings.
