A special brain scan may help show how fast a glioma is growing

Original title: Gliomas grading prediction using multicenter 3T Magnetic Resonance Spectroscopy.

How far along is this research?

This was tested in people. That is the most reliable kind of research we share.

This looked back at scans from people, but it is not a proven test yet.

The short version

A scan that measures brain chemicals may help doctors judge 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 without surgery.

What was studied. Researchers looked back at scan records from 60 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 patients at 3 hospitals. The scan, called MRS, measures chemicals in brain tissue. They tested 4 chemical measures.

What they found. Two of the chemical measures were different in slow growing and fast growing gliomas. When checked, these measures were right about 75% of the time. The team set a cutoff using two hospitals, then tested it at a third. One measure was right 77.78%, 100%, and 65% of the time.

What this means, and what it doesn't

What it could mean: Doctors may be able to use this scan to judge a tumor's grade. That could help with diagnosis and planning care. This type of scan is already used in brain care today.

What it doesn't mean: This is not a treatment, and it is not a cure. The study only looked back at old scan records from a small group. The results were not the same at every hospital. Much more work is needed before one shared rule can be used everywhere.
