This was tested in people. That is the most reliable kind of research we share.
This was a look back at scans from real patients, so it is not yet a tool doctors can use.
The short version
Researchers used computer analysis of MRI scans to guess a brain lymphoma's subtype without taking tissue.
What was studied. Researchers looked back at scans from 160 people with confirmed primary central nervous system lymphoma, a lymphoma that starts in the brain or spinal cord. They fed details from four kinds of MRI pictures into computer programs and asked the programs to predict two subtypes of the tumor.
What they found. The programs picked out 12 scan details to predict one subtype, and seven scan details to predict the other. Both of the best programs were right more often than not when tested on scans they had not seen before. The programs did better at predicting the germinal center B-cell-like subtype than the double-expression subtype.
What this means, and what it doesn't
What it could mean: Doctors currently learn a lymphoma's subtype by testing tumor tissue. If work like this holds up, an MRI might one day give doctors a hint about the subtype earlier, and with less testing. That could help with planning. It does not change how your subtype is found today.
What it doesn't mean: This is not a treatment, and it is not a cure. Nothing here says anyone lived longer or felt better. The team looked back at scans that were already taken, at one group of patients. The computer programs were only checked against that same group, not tested at other hospitals or in day to day care. Tissue testing is still how the subtype gets confirmed. This is early work and it is a long way from your clinic.
