This was tested in people. That is the most reliable kind of research we share.
This was a look back at old scans in a small group, and the tool is not in use yet.
The short version
A scan taken about 6 months after treatment may help show which tumors grow later.
What was studied. Fifty-four people with a meningioma near the base of the brain took part. All had Gamma Knife radiosurgery, with a scan before and about 6 months after.
What they found. By 3 years, 9 tumors had grown. 25 stayed the same, and 20 got smaller. A computer model that compared the before and after scans did well at telling apart the tumors that grew from the ones that did not.
What this means, and what it doesn't
What it could mean: If this holds up, an early scan could show who needs closer follow up. Those people could be watched more often, and other people could be checked less.
What it doesn't mean: This is not a treatment, and it is not a cure. It is an early test of a computer tool, not proven care. The tool was only checked on this one group of scans. It has not been tried on a new group of patients yet. Nothing here changes what happens at your appointments today.
