Do I need to fast for my PSMA PET Scan?

No. There is no need to fast for your PSMA PET Scan. Please see our question above for a full description about PSMA PET Scan preparation. Greater than 99% of all ‘regular’ PET scans are performed using something called “FDG” which looks to the body much like regular sugar. Therefore, fasting and other special preparation instruction must be followed for that type of PET Scan, but not for PSMA Pet Scans. PSMA, the PSMA agent used for your PSMA PET Scan, does not require any fasting or special preparation instructions.
