This was tested in people. That is the most reliable kind of research we share.
This is early software tested on stored scan files, not with real patients.
The short version
Researchers built a small computer program that outlines brain tumors on MRI scans using an ordinary laptop, and it finished each scan in under 10 seconds.
What was studied. Researchers built a computer program called GMANet. It reads MRI scans and marks where a glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary is. They tested it on two public sets of stored brain scans, called BraTS2019 and BraTS2021.
What they found. The program scored 92.45% and 90.93% on the two scan sets for outlining the whole tumor. It scored 86.28% and 84.72% for the tumor core, and 78.42% and 76.68% for the enhancing part of the tumor. On a normal laptop, it took 8.49 s to read one scan.
What this means, and what it doesn't
What it could mean: Most tumor-reading programs need costly graphics hardware. Many clinics and small hospitals do not have it. A tool like this could one day help those places spot a tumor faster and send a patient on sooner. The researchers see it as a first quick look, with a stronger program doing the careful work later.
What it doesn't mean: This is not a treatment. It does not shrink a tumor or help you live longer. It is not a cure, and it does not promise one. The tool was only tried on stored scans, not with real patients in a clinic. The authors say it still needs to be tested in real care before anyone can rely on it. No doctor can use this today.
