This was tested in people. That is the most reliable kind of research we share.
Doctors looked back at scans from past patients, so it is not proven yet.
The short version
A special MRI scan may help doctors tell a brain tumor from a look-alike spot.
What was studied. Doctors looked back at brain scans from 63 patients with unclear masses. A special MRI test measured natural chemicals inside each spot.
What they found. One chemical measure told the two groups apart. It was low in fast-growing gliomas and higher in the look-alike spots that are not cancer. Using a set cutoff, the test pointed to a glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary 72.7% of the time, and correctly cleared the look-alike spots 93.3% of the time.
What this means, and what it doesn't
What it could mean: If a brain scan is unclear, this test may give doctors more to go on. It might help them plan next steps, such as a biopsy. Ask your care team which scans and tests fit your case.
What it doesn't mean: This is not a treatment and not a cure. It is a way to help read a scan, nothing more. The study looked back at past patient scans, which is early evidence. The test was also wrong in some cases. Bigger studies at more hospitals are needed before this becomes normal care.
