What Radily gives back
Your chest CT report says
Scattered ground-glass opacities are noted in the bilateral upper lobes measuring up to 8mm. No consolidation, pleural effusion, or pneumothorax.
Radily explains
Your scan shows some small hazy areas in the upper part of both lungs. There is no solid patch of the kind pneumonia makes, no fluid around the lungs and no collapsed lung.
Ask your doctor: what might be causing the hazy areas, and do I need a follow-up scan?

Why the radiologist wrote it that way
A report has two halves. The Findings section is an exhaustive inventory of everything observed, including everything normal, written for completeness. The Impression is where the radiologist stands back and says what it all means. Referring doctors frequently read it first.
Is this good or bad news?
If a report has frightened you, it is worth checking whether the alarming sentence came from Findings or from Impression. Findings describe in isolation and without context — a phrase there can sound severe while the radiologist has already judged it irrelevant and left it out of the conclusion. The Impression is the considered answer to the question your doctor asked.
What it does not mean
- A guess or an opinion in the casual sense. It is the formal conclusion.
- That the Findings section does not matter — but it is written for a different reader.
Where you will see it
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
- Clinical correlation is recommendedThe radiologist is saying: here is what the pictures show, and now the doctor who knows your symptoms needs to decide what it means for you.
- Incidental findingSomething the scan picked up that has nothing to do with the reason you were scanned.
- Consistent withThe appearance fits the named condition — usually one your doctor already suspected.
- Status postSimply means "after". You have had the procedure or operation named.
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.
