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
On MRI these show as small bright areas in the white matter. Radiologists name the accepted mechanism — reduced flow through tiny vessels over time — which is why the frightening word "ischemic" appears. You may also see "chronic microvascular changes" or "white matter hyperintensities" for the same finding.
Is this good or bad news?
The wording is far more alarming than the finding usually is. These are present in a large share of people over fifty, including many with no symptoms whatsoever, and they are routinely described as an expected part of ageing. Their significance depends on how extensive they are and on your blood pressure, cholesterol, diabetes and smoking — which is why this finding is often a prompt to look after those things rather than a cause for alarm.
What it does not mean
- That you have had a stroke. A stroke is a distinct finding and would be named as one.
- That you are developing dementia. These changes appear in very many cognitively normal people.
- That brain tissue is dying now. "Chronic" changes are old and static.
Where you will see it
Words in this phrase
- IschemiaReduced blood flow to tissue or organs.
- White matterThe inner tissue of the brain containing nerve fibers.

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
- Cannot be excludedThe images are not able to completely rule this out — which is a statement about the limits of the scan, not a suggestion that it is likely.
- NonspecificThe finding is real, but its appearance is not distinctive enough to say what is causing it.
- Small pleural effusionA small amount of fluid has collected in the space between the lung and the chest wall.
- Hepatic steatosisFat has built up in the liver — commonly called fatty liver.
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.
