This was tested in people. That is the most reliable kind of research we share.
This only looked at brain scans already taken in people, and it is not a treatment.
The short version
Brain scans may show how a glioma: A tumor that starts in the glial cells. Those are the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4. The grade says how the tumor is expected to act. See the glossary changes the way the brain is wired.
What was studied. Researchers used resting brain MRI scans from 306 people with confirmed glioma: A tumor that starts in the glial cells. Those are the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4. The grade says how the tumor is expected to act. See the glossary at two hospitals. They measured brain activity inside each tumor and in the tissue around it.
What they found. They created two new measures of brain wiring. Weaker activity inside the tumor went along with worse outcomes, while more preserved wiring went along with longer survival. The measures were also linked to thinking, language, and the tumor's biology.
What this means, and what it doesn't
What it could mean: This is a research tool, not a treatment. One day these scan measures might help doctors judge how a tumor is likely to behave. For now, it does not change the care you get.
What it doesn't mean: This does not mean a new treatment, and it is not a cure. No one was given a new drug or therapy here. It was a look at scans and records, not a trial. The authors say these measures must be tested in new studies first. They also note the scans are based on blood flow, so the results are not exact.
