Prostate specific membrane antigen (PSMA) is expressed in normal prostate epithelial cells and strongly up regulated in initial and advanced prostate carcinoma. Therefore
PSMA is an attractive molecular target for the detection of primary and metastatic lesions. It plays an important role in the diagnosis
staging
prognostic evaluation and targeted treatment in prostate carcinoma patients. This review will summarize the progress of small molecular radionuclide probes
