This was tested in people. That is the most reliable kind of research we share.
This was a look back at scans patients already had, not a test of a new treatment.
The short version
A special brain scan found most fast-growing tumors, but it called some infections tumors too.
What was studied. Doctors looked back at records of 53 patients with a spot or mass in the brain. Everyone had tissue tested, so the true diagnosis was known. The team checked how well a special MRI scan, called magnetic resonance spectroscopy, matched the tissue results.
What they found. Tissue tests showed a high-grade 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 in 40 of 53 patients. The scan called 42 people high-grade glioma and 11 not high-grade glioma. Seven of the scan's tumor calls were wrong. Three of those were cancer that spread from somewhere else, three were abscesses, and one was another kind of problem.
What this means, and what it doesn't
What it could mean: A doctor may use this scan as one clue, not the final answer. Tissue testing is still what confirms what a mass really is. If the scan points to a high-grade 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, an infection or spread from another cancer can still be the cause.
What it doesn't mean: This does not mean the scan can take the place of a tissue test. It was a small look back at 53 past patients, not a new treatment or a new test. It does not change the care you get today, and it is not a cure or a promise about how you will do. The computer program the team tried did not do better than the doctors reading the scans.
