- Tested in people
This was tested in people. That is the most reliable kind of research we share.
It has been used in people, but only in an early look back at past scans.
The short version
A new dye used with a PET scan made these brain tumors stand out clearly.
What was studied. Doctors looked back at scans from 37 people with a known or suspected meningioma. Each person had a PET/CT scan with a new dye called [18F]SiTATE.
What they found. The scan showed meningioma signal in 32 of 37 exams, or 86.5%. It found 69 tumors in all, and no one had side effects from the dye. Normal brain tissue barely lit up, so the tumors stood out.
What this means, and what it doesn't
What it could mean: Doctors may get a clearer view of where a meningioma sits. That kind of clear view can help with planning surgery or radiation. The dye itself is not a treatment. It only helps doctors see the tumor.
What it doesn't mean: This does not mean the dye is ready for your clinic. Doctors only looked back at scans people already had. It was not a planned trial, and it was not tested head to head against the dyes used now. It is a scan dye, not a treatment, and it is not a cure.
