This was tested in people. That is the most reliable kind of research we share.
This was a look back at past patient records, not a new treatment.
The short version
After brain surgery, the shape of a spot on the MRI may hint at who gets worse.
What was studied. Doctors looked back at records for 139 people who had surgery for a glioma: A tumor that starts in the glial cells. Those are the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4. The grade says how the tumor is expected to act. See the glossary. The tumors sat in parts of the brain that control key functions. Each person had an MRI soon after surgery, and the spots were sorted into two shapes.
What they found. Spots showed up on the scans of 44 of the 139 people. One shape, called sector-shaped, was linked to getting worse. The other shape, called rim-shaped, carried about the same risk as a clear scan. 61% of the people who got worse had a clear scan.
What this means, and what it doesn't
What it could mean: The shape of a spot may matter more than just having a spot. Doctors may watch some people more closely based on that shape. But a clear scan does not mean you are safe. Most people who got worse had a clear scan.
What it doesn't mean: This does not mean a scan can tell what will happen to you. It was one look back at past records at one place, not a planned trial. The authors say larger studies are needed to be sure. This is not a new treatment and not a cure. It does not change the care you get today.
