Prostate-specific membrane antigen (PSMA) PET has been recently introduced for the diagnosis of patients with metastatic prostate cancer (PCa). Until today, staging of patients with PCa relied mostly on morphologic features, such as size or shape, resulting in low detection rates in disease recurrence. PSMA PET imaging provides molecular information and, in combination with conventional imaging, offers improved sensitivity and specificity. This article discusses the benefits and limitations of PSMA imaging in the setting of primary staging and detection of recurrent disease in comparison with standard-of-care imaging techniques.
