- Review
- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This looked back at old scans, and it still needs testing in new patients.
The short version
A computer program read brain scans to guess how fast a tumor was growing, before surgery.
What was studied. Researchers looked back at scans from five hundred and twelve people with meningioma. The scans came from four hospitals. A computer program split each tumor into four smaller zones and studied the pattern in each one.
What they found. The program was built with one group of patients and then tested on two other groups. It matched the lab result well in all three groups. Details from the tumor zones mattered most. They made up 9 of 15 of the features the program used.
What this means, and what it doesn't
What it could mean: Right now, doctors learn how fast these tumor cells grow only after surgery. They test the tissue that was removed. If this work holds up, a scan might give a hint sooner. That could help a care team plan before an operation.
What it doesn't mean: This does not mean a scan can replace the lab test. The team looked back at old scans, so this is not proof. They say it still must be tested going forward in new patients. It is a research tool, not something you can ask your doctor for today. It is not a treatment, and it is not a cure.
