This was tested in people. That is the most reliable kind of research we share.
This was a look back at scans already taken in children, not a new treatment.
The short version
MRI pictures may help doctors guess a child's brain tumor type before surgery.
What was studied. Doctors looked back at records of 34 children with a tumor in the thalamus: A part deep in the brain, near its center. It passes messages from the senses and the body on to the rest of the brain. See the glossary, a deep part of the brain. There were 12 boys and 22 girls, with an average age of 10.4 years. The team compared how each tumor looked on MRI with what lab tests later showed.
What they found. Two tumor types were the most common. Pilocytic astrocytomas made up 28% of the group, and diffuse midline gliomas made up 24%. The two types did not look the same on the scans. Pilocytic astrocytomas had clear edges and a fine, brush-like pattern. Diffuse midline gliomas had fuzzy edges and patchy spots.
What this means, and what it doesn't
What it could mean: The look of a scan may help a care team plan surgery better. It may help them choose between removing as much tumor as is safe, or taking a small sample first. Families may get an idea of the tumor type sooner.
What it doesn't mean: This does not mean a scan can replace testing the actual tumor tissue. It was a look back at past records of one small group of 34 children. Some of the differences the team measured were not strong enough to be sure. This is not a new treatment, and it is not a cure. Larger studies are needed before scans alone guide this choice in everyday care.
