- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This was a first study in people, and it tested a scan rather than a treatment.
The short version
Doctors tested a special MRI scan to see if it could tell how aggressive a meningioma is before surgery.
What was studied. Researchers scanned 107 people who had a meningioma, a tumor that grows in the lining around the brain. All of them had this special MRI, called time-dependent diffusion MRI, before their surgery. Of the 107 people, 78 were women, and the average age was 55.7 years.
What they found. Adding the special scan to a regular MRI worked better at judging the tumor grade than a regular MRI by itself. The combined scans also worked best at sorting out which type of meningioma a person had. The scan measurements had only weak links to how fast the tumor cells were dividing.
What this means, and what it doesn't
What it could mean: If this holds up, doctors might learn more about a meningioma from a scan before surgery. That could help with planning. Right now it is a research tool, not part of normal care.
What it doesn't mean: This does not mean there is a new treatment. Nothing here was tested as therapy, and it is not a cure. This was one study at an early stage, done in people before their surgery, and the scan was compared against results doctors already had. It is far from something you can ask for at a normal scan appointment. Tissue taken during surgery is still how the tumor type and grade get confirmed.
