This was tested in people. That is the most reliable kind of research we share.
This was a small, early study in people, and it tests a scan, not a treatment.
The short version
A small study tested an MRI scan that may help doctors tell two brain tumor types apart.
What was studied. Doctors scanned 18 people who had a new brain mass and had not been treated yet. Of them, 11 had a fast growing brain tumor called a high grade 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. The other 7 had cancer that had spread to the brain from somewhere else.
What they found. The scan measured how well the brain's protective lining was working. In the tissue right around the tumor, the two tumor types gave different results. Using this new scan together with an older scan told the two types apart a little better than either scan alone.
What this means, and what it doesn't
What it could mean: It can be hard to tell these two tumor types apart on a scan. This method might one day give doctors one more clue. For now it is only an early test, and it does not change care today.
What it doesn't mean: This is not a new treatment, and it is not a cure. It is a way of taking pictures, not a way of treating a tumor. The study was very early and included only a small number of people. Doctors do not use this scan this way in everyday care. Bigger studies at more hospitals are needed first.
