- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This was only tested on saved scans with computers, not used in patient care.
The short version
Researchers tested two computer programs to see which one spots brain tumors on scans better.
What was studied. The team used free, public sets of MRI scans of two tumor types, meningioma and glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary. They tuned the settings of one computer program, then swapped in a different design and compared the two.
What they found. The first program did best overall. On scans from a new outside source, it scored 79.0% and beat the other program by 10.1%. The other program was steadier when one of its settings was changed.
What this means, and what it doesn't
What it could mean: Someday, tools like these might help doctors spot tumors on scans. This study helps computer builders choose how to design such tools.
What it doesn't mean: This does not mean a computer can find your tumor today. It was only tested on saved scans, not on patients in care. It is not a treatment, and it is not a cure.
