This was tested in people. That is the most reliable kind of research we share.
It was an early test on past scans at one hospital, not something you can get.
The short version
A computer tool read brain MRI scans and usually told real tumor growth apart from changes caused by treatment.
What was studied. Researchers built a computer tool that reads MRI scans taken after brain surgery. They used scans from 124 people with glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary, covering 164 scan visits, all done at one center.
What they found. The tool did well at one job. It told real tumor growth apart from swelling and other changes caused by treatment. It did not work for three other jobs. It could not predict a gene marker called MGMT promoter methylation: MGMT is a gene whose protein repairs damage to a tumor's DNA. Methylation turns it down. Your report says how much, and your team uses that when they choose chemotherapy. The line between high and low is not settled. See the glossary, short term survival, or the choice to give radiation. Those answers were about as good as a guess.
What this means, and what it doesn't
What it could mean: Doctors often struggle to tell regrowth from treatment changes on a scan. A tool like this might one day help with that hard call. That could mean less waiting and fewer biopsies. It is not part of anyone's care yet.
What it doesn't mean: This is not a test you can ask your doctor for. It was a first proof of concept at one hospital, using one brand of scanner. The authors say it must be tested at many other centers first. The tool does not treat the tumor, and it is not a cure. Nothing about your care changes today.
