- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This computer tool was only tested on old scans and is not used in patient care.
The short version
A computer program found tumors on brain scans better when it also learned about healthy brain parts.
What was studied. Researchers trained a computer program to find cancer that has spread to the brain on MRI scans. They used 301 scans with 1111 tumors marked. One version learned only the tumors, and the other also learned important healthy brain parts. Both were tested on 100 cases with 421 tumors.
What they found. The version that also learned healthy brain parts did better on several checks. It made fewer false alarms. Some spots first counted as false alarms turned out to be real tumors: 47 of 151 for this version, but only 22 of 231 for the other.
What this means, and what it doesn't
What it could mean: Someday, tools like this might help doctors read brain scans more accurately. That could help people who need many MRI scans to watch for new tumors.
What it doesn't mean: This is early computer research that used past scans. Doctors are not using this tool in everyday care. It does not treat tumors, and it is not a cure. More testing is needed before doctors could trust it.
