This was tested in people. That is the most reliable kind of research we share.
This was an early test on old scans from children, not a tool doctors can use yet.
The short version
Researchers tested a computer program that tries to trace the edges of a child's brain tumor on one type of MRI scan.
What was studied. This study looked back at scans from 107 children with brain tumors. Researchers trained a computer program to mark the tumor's edges using only diffusion MRI scans.
What they found. The computer could mark tumor edges on its own. But its outlines did not match the ones drawn by hand by experts closely enough. The researchers say more work is needed before this is good enough to use.
What this means, and what it doesn't
What it could mean: Right now, marking a tumor's edges on a scan is slow. It takes a trained expert, and two experts may not agree. A tool like this could one day help doctors do that step faster. It is not a treatment, and it would not change what care a child gets today.
What it doesn't mean: This does not mean a computer is reading scans in the clinic. It was an early test on scans that were already taken. The program was not accurate enough yet, and the researchers say so. This is not a treatment, and it is not a cure. It is far from everyday care.
