Pet Scan Question

Posted by broderbund1 @broderbund1, 6 days ago

Hi -

I was at MSK last week. Radiologist's nurse/assistant provided me with an order for a Pet Scan back in Florida. When I called the hospital today to schedule the order reads PET/CT Head/Neck/Cap - GAPSMA.

Just wanted to make sure she wrote it down correctly as I thought it might say PSMA Pet Scan???

Interested in more discussions like this? Go to the Prostate Cancer Support Group.

GA is probably for Gallium being specified as the radioactive agent used with the PSMA.

There are 3 PSMA PET scans:
> 68Ga-PSMA-11 (Gallium68) PSMA PET: (trade name: Illuccix®).

> F18-DCFPyL (Piflufolastat) PSMA PET: (trade name: PYLARIFY®).

> F-18-Flotufolastat PSMA PET: (trade name: Posluma®).

As @jim18 mentioned, “GAPSMA” is likely their shorthand for the Gallium68 PSMA PET.
