This was tested in people. That is the most reliable kind of research we share.
This was an early look at scans in people, and it is not a treatment.
The short version
A special MRI scan picked up clear differences between parts of a brain tumor.
What was studied. Doctors looked back at scans from 120 people with 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, a kind of brain tumor. They used a special MRI method that measures tiny magnetic changes in different parts of the tumor and the tissue around it.
What they found. Faster growing tumors showed more of one magnetic signal in the main tumor tissue. Slower growing tumors showed less of it. People with more of this signal in the tumor tissue tended to live a shorter time. In 6 more people, the scan signal matched the amount of iron found in their real tumor tissue.
What this means, and what it doesn't
What it could mean: This scan may one day give doctors more clues about a tumor before surgery. It could help them learn about the tumor type and how fast it grows, using a scan instead of more tests.
What it doesn't mean: This is not a treatment and it is not a cure. It is early research that mostly looked back at old scans. The method is not part of normal care, and most hospitals cannot do it. It cannot tell any one person how long they will live. Much more work is needed first.
