This was tested in people. That is the most reliable kind of research we share.
This study looked back at scans from people, and the tool is not used in regular care yet.
The short version
Doctors tested a simple scoring tool that uses brain scans to spot glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary.
What was studied. Researchers looked back at brain scans from 108 people with brain tumors. Two readers scored the person's age and features of the scan. They did not know the lab results.
What they found. Of the 108 cases, 85 were glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary and 23 were a different tumor type. The tool caught 97% to 99% of the glioblastoma cases. One reader who was still in training did better with the tool. Their correct answers rose from 84.3% to 87.0% with one model and 91.7% with the other.
What this means, and what it doesn't
What it could mean: A tool like this may help doctors read brain scans with more confidence. It may help most with tumors that look unusual on a scan. Lab tests on tumor tissue are still what confirm the diagnosis.
What it doesn't mean: This is not a treatment and it is not a cure. It is an early check of a scan tool, not something used in everyday care. The study looked back at past scans from one group of people. The tool does not replace the tissue tests that name the tumor. More study is needed before clinics can rely on it.
