This was tested in people. That is the most reliable kind of research we share.
This was an early test of computer software on stored scans, not something a patient can get today.
The short version
Researchers built a computer tool that draws the edge of a brain tumor on ultrasound pictures taken during surgery.
What was studied. Surgeons use ultrasound during brain surgery, but the pictures are grainy and hard to read. Researchers built computer software that finds the tumor in those pictures and draws a line around its edge. They tested it on a public set of ultrasound scans and on two other patient cases.
What they found. The software found tumor areas about as well as other computer tools already in use. It also picked up more of the tumor area, and the researchers checked how often it marked areas that were not tumor. Junior surgeons were asked to outline tumors. Their outlines matched a senior expert's outline 76.56% of the time on their own, and 90.60% of the time after they looked at the software's outline.
What this means, and what it doesn't
What it could mean: If this works in bigger studies, it could help surgeons see the edge of a tumor more clearly while they operate. That could help less experienced surgeons read ultrasound pictures. This is a tool for the operating room, not a drug or a treatment you would take.
What it doesn't mean: This does not mean the software is ready for your surgery. It was tested mostly on stored scans, plus two other cases. It has not been tested at many hospitals or with many different surgeons. It is not a treatment and it is not a cure. The researchers say more testing is still needed.
