This was tested in people. That is the most reliable kind of research we share.
This is a planning tool tested on old patient scans, not a treatment you can get.
The short version
A computer tool learned to draw the radiation target area about as well as doctors do.
What was studied. Researchers built a computer model that draws the target area for 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 radiation. They tested it on 93 past glioma cases treated by three doctors at one hospital.
What they found. Doctors rated both the computer drawings and the hand drawings. Both got the same average score of 2.3, on a scale where 3 means acceptable. The three doctors drew the area in different ways, most of all near the brain stem and the fluid spaces in the brain. A second model picked the right doctor's style 80% of the time.
What this means, and what it doesn't
What it could mean: This does not change any treatment you get. It is a tool for the people who plan radiation. Over time it could help doctors check their work and agree more on where to aim the radiation.
What it doesn't mean: This is not a new treatment and it is not a cure. It does not make radiation work better or cause fewer side effects. The tool was only tested on old scans from one hospital, with three doctors. It has not been used to plan care for new patients, and it may not work the same way somewhere else.
