AB  - PET imaging with the prostate-specific membrane antigen (PSMA)-targeted radioligand (68)Ga-PSMA-11 is regarded as a significant step forward in the diagnosis of prostate cancer (PCa). More recently, a PSMA ligand was developed that can be labeled with (68)Ga, (111)In, (177)Lu, and (90)Y. This ligand, named PSMA-617, therefore enables both diagnosis and therapy of PCa. The aims of this evaluation were to clinically investigate the distribution of (68)Ga-PSMA-617 in normal tissues and in PCa lesions as well as to evaluate the radiation exposure by the radioligand in PET imaging.Nineteen patients, most of them with recurrent PCa, were referred for (68)Ga-PSMA-617 PET/CT. The quantitative assessment of tracer uptake of several organs and of 53 representative tumor lesions was performed in 15 patients at 1 and 3 h after injection. In 4 additional patients, the same procedure was conducted at 5 min, 1 h, 2 h, 3 h, 4 h, and 5 h after injection. On the basis of the data for these 4 patients (mean injected dose, 231 MBq), the radiation exposure of a (68)Ga-PSMA-617 PET/CT was identified.Intense tracer uptake was observed in the kidneys and salivary glands. In 14 of 19 patients (73.7
