This was tested in people. That is the most reliable kind of research we share.
This was a small, early look at a scan tool in people, not a treatment.
The short version
A newer PET scan tracer lined up well with what doctors saw under the microscope.
What was studied. Doctors studied 12 patients with meningioma, a type of brain tumor. Of those patients, 42% were female. The team compared PET scans using a tracer called SiTATE with tests done on the tumor tissue after surgery.
What they found. The scan results matched the tissue results closely. Tumors that showed more of the target on their cells also showed more tracer on the scan. But the scan did not measure tumor size well every time. One way of reading the scan came up short in four cases. Another way came up short in two tumors.
What this means, and what it doesn't
What it could mean: This tracer may help doctors see meningiomas more clearly on a scan. It is already used in some clinics today. It is not approved by the FDA or the EMA. It is a scan tool, not a treatment.
What it doesn't mean: This does not mean a new treatment or a cure. Nothing here changes how a tumor is treated. The study was small and early, with only 12 patients. It was a first look, not proof. The scan also did not measure tumor size well in every case. More studies are needed before this changes everyday care.
