None:
68 Ga-Prostate-Specific Membrane Antigen (PSMA) is excreted mainly through the urinary system, but also partly through biliary system. Herein, we present such a case in a man with prostate cancer. The 68 Ga-PSMA PET/CT revealed increased uptake of 68 Ga-PSMA in bone metastases. Besides, increased 68 Ga-PSMA uptake in the common hepatic duct and common bile duct was observed, which resolved spontaneously in the delayed imaging.
