This was tested in people. That is the most reliable kind of research we share.
This looked back at scans already collected from people, so it is not a tested tool yet.
The short version
Researchers checked if fewer MRI scans could still help tell brain tumor types apart.
What was studied. Scientists used scan data from 501 people with diagnosed brain cancer from a public dataset. They fed features from six MRI scan types into computer models. The models tried to sort tumor grade, final diagnosis, and IDH gene change: A small change in a tumor's IDH gene. It is the first thing your team looks at when naming an adult glioma, and it can affect which treatments are offered. Your pathology report says whether your tumor has it. See the glossary status.
What they found. One scan type called FLAIR: One of the picture settings used in an MRI. It dims the fluid in the brain so that swelling and other changes show up more clearly. See the glossary sorted tumor grade correctly 57.4% of the time. A scan called ASL sorted glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary from astrocytoma correctly 81.5% of the time. A T1w scan sorted IDH gene change: A small change in a tumor's IDH gene. It is the first thing your team looks at when naming an adult glioma, and it can affect which treatments are offered. Your pathology report says whether your tumor has it. See the glossary status correctly 66.7% of the time. Using all the scans together did not work much better than the best single scan.
What this means, and what it doesn't
What it could mean: This is early work on scan protocols, not on treatment. If it holds up, it might help shorten some MRI visits. Your own diagnosis still comes from your doctors and, when needed, from tissue tested in a lab.
What it doesn't mean: This does not mean your MRI plan should change. The work was done on stored scans from a past dataset, not in a live clinic test. The accuracy numbers are far from perfect, and the grade result was barely better than a coin toss. This is not a treatment and not a cure. Nothing here promises a better outcome for any person.
