In plain language
The appearance leans towards a particular diagnosis and needs to be settled, usually by a biopsy or a different test. It is stronger than "cannot be excluded" and weaker than a diagnosis: radiologists reserve it for findings that should not be left alone.

Where you'll see this
The impression, where the report is naming what it thinks is most likely and what to do next.
Your report may word it “Concerning for” or “Worrisome for”. These mean the same thing.
Questions worth asking your doctor
- How likely is the thing you are suspicious of, roughly?
- What test settles it, and how soon should it happen?
- What happens between now and then if my symptoms change?
How often does this turn up?
Suspicious for is a deliberate and fairly high level of concern in radiology’s graded vocabulary. It sits above equivocal and cannot be excluded, and just below consistent with. When a radiologist writes it, they are saying the appearance has features that point towards a specific diagnosis strongly enough that it should be pursued.
Does it mean something is wrong?
This is one of the phrases where the plain reading is the right one. It is chosen precisely when a radiologist wants the referring doctor to act, and it usually comes with a recommendation for what should happen next. It is not a diagnosis — imaging alone rarely is — but it is not a hedge either, and treating it as one would be a mistake. Where the suspicion is high and time-sensitive, the radiologist normally telephones as well as writing it.
What to do with it
Something specific almost always follows, and the report usually names it: a biopsy, a different scan, a specialist referral, or an urgent appointment. The pathway depends on what is suspected. If your report contains this phrase and you have not been contacted with a plan within a reasonable time, that is worth chasing actively rather than waiting.
Frequently asked questions
- Does suspicious for mean I have it?
- No, but it means the radiologist thinks it likely enough to be pursued. Imaging can strongly suggest a diagnosis without establishing it, which is why the phrase is nearly always followed by a recommendation for the test that would.
- How is it different from cannot be excluded?
- They sit at opposite ends of the confidence scale. Cannot be excluded means this study could not rule something out. Suspicious for means the appearances actively point towards it. One describes a limit, the other a positive impression.
- What should I do if I see this?
- Make sure a plan exists. The phrase is written to prompt action, so the report normally names a next step. If nothing has been arranged, contacting your doctor directly is reasonable rather than over-anxious.
