- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This tool is already approved in Europe and used in some operating rooms, but it is not standard care in most places.
The short version
A computer tool helped doctors tell during surgery if a biopsy sample held tumor.
What was studied. Doctors at one hospital looked back at 89 patients who had a brain biopsy. An AI program checked 204 scans of their tissue, taken with a special imaging tool during surgery.
What they found. At first, the AI was right about tumor tissue 80.9% of the time. After a brain pathologist looked again at the scans the AI got wrong, accuracy rose to 94.1%. The AI did worst on tissue that was not tumor, where it was right 62.5% of the time.
What this means, and what it doesn't
What it could mean: A tool like this may give a surgeon a fast answer while the biopsy is still happening. That could help the surgeon know the sample is useful before closing up.
What it doesn't mean: This is not a treatment, and it is not a cure. The tool only helps check tissue during surgery. It does not say which tumor type a person has. This was a look back at records at a single hospital, and the tool still needed an expert to catch its mistakes. Most hospitals do not use it today.
