This was tested in people. That is the most reliable kind of research we share.
This was only tested on stored scans by a computer, not in real care.
The short version
Researchers built a computer tool that studies MRI scans to guess a brain tumor's gene traits.
What was studied. Scientists trained a computer program on brain MRI scans from 2270 people. The scans came from public collections gathered at many different hospitals.
What they found. The tool picked out several tumor markers, including IDH gene change: A small change in a tumor's IDH gene. It is the first thing your team looks at when naming an adult glioma, and it can affect which treatments are offered. Your pathology report says whether your tumor has it. See the glossary, 1p/19q co-deletion: Two pieces of two chromosomes are gone. They are gone from the tumor cells. A glioma can have this change. If it has an IDH gene change too, it is called an oligodendroglioma. See the glossary, and 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. It also judged the tumor's grade. The team reports it worked about the same for each marker. It could also flag its own guesses when it was not sure.
What this means, and what it doesn't
What it could mean: Right now doctors learn these markers from a piece of tumor taken in surgery. Surgery carries risk, and one small piece may not match the whole tumor. A tool like this might one day give some of those answers from a scan.
What it doesn't mean: This does not change how your tumor is tested today. The tool was only run on stored scans, not in a real clinic. No one's care was decided with it. It is not a treatment, and it is not a cure. Much more testing is needed before a doctor could use it.
