This was tested in people. That is the most reliable kind of research we share.
This was a computer test on scans already taken, not something used in care yet.
The short version
Researchers built a computer tool that looks for radiation damage on brain MRI scans.
What was studied. Radiation treatment can damage healthy brain tissue. Researchers trained computer programs to find that damage on MRI scans, using scans from 52 patients. They then tested the programs on 29 other patients with 39 damaged spots.
What they found. The two best programs found all of the large damaged spots, or 100% of them. They found fewer of the small spots, 78 and 67% of them. Other programs found almost none of the small spots. The full tool was also tested on 115 spots and usually told radiation damage apart from tumor growth.
What this means, and what it doesn't
What it could mean: Today, doctors often need brain surgery to tell radiation damage from a growing tumor. A tool like this may one day help doctors answer that from a scan instead. Small spots are still hard for it to find.
What it doesn't mean: This does not mean the tool is ready for your care. It was tested on stored scans, not in a real clinic visit. It is not a treatment and it is not a cure. It still missed some small areas of damage. Your doctor is the one who reads your scan and decides what it means.
