- Tested in people
This was done on cells in a lab, not in people. It is a very early step.
This was only tested on stored scan images, not with patients.
The short version
Researchers built a computer program that looked at MRI scans and named the tumor type.
What was studied. The team tested a computer program on 7,023 MRI images from a public collection. The scans were grouped as glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary, meningioma, pituitary tumor, or normal.
What they found. The program first sharpened the scans so tumor shapes stood out. The best setup gave the right answer 96.58% of the time. Picture checks showed the program looked at the tumor area, not the background.
What this means, and what it doesn't
What it could mean: A tool like this might one day help doctors read scans faster and more evenly. It is small enough to run on a regular computer, so clinics with less equipment could use it.
What it doesn't mean: This is not a treatment, and it is not a cure. It is early computer work done on saved scan files, not with real patients in a clinic. No one has shown it helps people get better care yet. Doctors still read the scans themselves.
