This was tested in people. That is the most reliable kind of research we share.
This was a first small test of a scan in 12 people, not a treatment.
The short version
Doctors tested a new kind of MRI scan on 12 people with glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary.
What was studied. Researchers used a special MRI scan on 12 people with confirmed glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary. The scan looks at oxygen in the blood and does not need dye.
What they found. The scan showed the biggest signal changes in the busiest part of the tumor. That part grows a lot of new blood vessels. The signal there was also the most uneven, more so than in swollen tissue or in healthy tissue on the other side of the brain.
What this means, and what it doesn't
What it could mean: This scan might one day help doctors see which parts of a tumor are most active. It could add to the scans people already get. It does not change care today.
What it doesn't mean: This is not a treatment, and it is not a cure. It was a first, small test in only 12 people. The scan is not part of normal care, and no one knows yet if it helps people live longer or feel better. Much more study is needed.
