Abstract

ABSTRACT; Prostate-specific membrane antigen (PSMA) PET/CT is an imaging technique that detects primary and metastatic prostate cancer and evaluates treatment effectiveness. The radioligands for PSMA PET/CT are known to have physiological off-target uptake in various tissues. These include the well-known off-target major and minor salivary glands. We report that, in addition to this location, radioligand uptake can be seen in the uvula, which we suggest is from salivary tissue in this location. PSMA uptake in the uvula is not reported in the literature and is a rare, but normal location for tracer biodistribution in some patients.
