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 test of a new treatment.
The short version
Doctors tested a scan-based grading system to plan surgery for tumors that sit next to a large vein in the brain.
What was studied. Doctors looked back at 62 parasagittal meningioma surgeries done by one surgeon at one hospital. They graded each tumor on scans using a system called SSIG, then compared the grades to how the surgery went.
What they found. The SSIG grade matched other ways of grading how much the tumor involved the vein. As the grade went up, surgery took longer. Blood loss and fluids given during surgery also went up. In the high-involvement group, 66.7% had a less complete removal strategy, compared with 13.6% in the low group. Problem rates after surgery were about the same in both groups. Follow-up lasted 13.3 months on average, and no tumor came back on scans by the last check.
What this means, and what it doesn't
What it could mean: If this holds up, a scan grade might help your surgeon plan ahead. It could give a better idea of how hard the surgery may be and how much tumor can safely come out. That may help you and your doctor talk about what to expect.
What it doesn't mean: This is not a new treatment, and it is not a cure. It was one look back at records from a single surgeon at a single hospital. The follow-up was short, so we do not know the long-term results. The authors say it still needs testing in bigger groups over more time before it can guide everyday care.
