This was tested in people. That is the most reliable kind of research we share.
It was tested in people, but it is still a research scan and not part of normal care.
The short version
A new kind of MRI scan helped doctors tell what type of brain tumor a person had, without surgery.
What was studied. Doctors studied 141 adults with diffuse glioma: A glioma whose cells spread out into the brain around it instead of staying in one lump. That is why the edge on a scan is not a clean line. See the glossary, a kind of brain tumor. In 56 people the tumor had a change in a gene called 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. In 85 people it did not. A special MRI scan split each tumor into three zones.
What they found. The zone based method guessed the 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 gene type better than looking at the whole tumor as one lump. One zone was tied to how fast the tumor cells were growing. People the method marked as high risk had their tumors start growing again sooner.
What this means, and what it doesn't
What it could mean: One day a scan like this might tell doctors about a tumor's genes before surgery. It would not need dye in a vein. For now it is a research tool, not part of normal care.
What it doesn't mean: This is not a new treatment. It is not a cure, and it does not change the care you get today. It was one study, and it needs much more testing. Doctors still check tumor tissue to know the gene type for sure.
