This was tested in people. That is the most reliable kind of research we share.
This study only tested computer models on old scans, not in real care.
The short version
Computer models read brain scans to guess how fast a tumor may grow.
What was studied. Researchers looked back at MRI scans from 455 people with a meningioma brain tumor. They built four computer models to guess the tumor grade before surgery.
What they found. Of the 455 tumors, 112 were a higher grade, or 24.6%. One model that outlines the tumor on the scan worked best at a new hospital. Mixing models together did not clearly beat that one model.
What this means, and what it doesn't
What it could mean: Doctors may one day use scans to help guess a tumor's grade before surgery. For now, the grade still comes from a tissue sample checked in a lab.
What it doesn't mean: This is not a new treatment, and it is not a promise of a cure. The models were tested on old scans, not in real clinics. They were right more often than chance, but they still made mistakes. No one should change their care based on this study.
