- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This was an early test on scans already taken from people, not a tool doctors can use yet.
The short version
Researchers tested a computer method that studies MRI scans to guess a brain tumor's type before surgery.
What was studied. Researchers looked back at MRI scans from 90 patients at one set of hospitals and 28 patients at another. They tested whether a special scan method, called SAGE, plus a computer program could tell three tumor types apart: meningiomas, tumors that spread to the brain from elsewhere, and gliomas.
What they found. The computer program split each tumor into three zones and looked at each zone. The best program from the first group of patients did worse when it was used on the second group of scans. A simpler version of the program actually did better on that second group.
What this means, and what it doesn't
What it could mean: If a method like this gets better, doctors might one day get a stronger hint about a tumor's type from a scan. That could help with planning before surgery. For now, this does not change how your tumor is diagnosed.
What it doesn't mean: This is not a treatment, and it is not a cure. It is not a test you can ask for today. It was an early study that looked back at scans already taken, at a small number of people. The method did not hold up as well on the second group of scans, so it is not reliable yet. Tumor type is still confirmed by doctors in the usual ways, including looking at tissue.
