What does “Trace” mean on a radiology report?
The smallest amount that can be seen — barely there.
Why the radiologist wrote it that way
The bottom of the radiologist’s volume scale, below "small". Used for fluid, for valve leakage on an echocardiogram, and for anything present in a quantity hardly worth measuring.
Is this good or bad news?
Generally the least significant grade available. A trace effusion or a trace of valve leak is frequently within the range of normal and often needs nothing at all. It gets written down because radiologists record what they see, not because it demands action.
What it does not mean
- The beginning of something that will grow.
- That a measurement was too difficult to take.

Words in this phrase
One phrase is not the whole report
What this sentence means for you depends on everything else your report says. Radily reads the whole thing and explains it in plain English — and can talk you through it on video, so you are not reading medical language alone.
Other phrases on your report
- No acute intracranial abnormalityThe scan found nothing new or urgent inside the skull — no bleeding, no swelling, no sign of injury needing treatment today.
- UnremarkableNormal. There was nothing worth remarking on.
- Mild degenerative changesOrdinary age-related wear in the joints or spine — the kind almost everyone develops, to some degree, as they get older.
- No acute cardiopulmonary processThe chest X-ray shows no new problem with the heart or lungs — no pneumonia, no fluid around the lungs, no collapsed lung, and a heart that looks a normal size.
This explains how a phrase is commonly used in radiology reports. It is not a diagnosis, not a reading of your scan, and not medical advice. Only your doctor can tell you what your own report means.
