This was tested in people. That is the most reliable kind of research we share.
This was an early test on stored scans from patients, not a treatment you can get.
The short version
Researchers tested a computer tool that reads brain scans and rates tumor change.
What was studied. Researchers used stored MRI scans from people with glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary in a public scan set. A computer tool read the scans and rated whether the tumor grew or shrank. Its ratings were compared with ratings made by a brain scan doctor.
What they found. The team used 542 scan timepoints, and 506 of them matched the doctor's notes. Across four rating groups, the tool and the doctor gave the same rating 48.1% of the time. At the last scan, they agreed 76.0% of the time about whether the tumor had grown. When the tool flagged a new spot, it was right 22.3% of the time.
What this means, and what it doesn't
What it could mean: This tool is not a treatment. It may help research studies measure tumor change in a steadier way. Right now it does not agree with doctors closely enough to be used on its own.
What it doesn't mean: This does not mean the tool is ready to help with your care. It was only tried on stored scans from one center, and not during real visits. It does not change any treatment, and it is not a cure.
