Imaging in prostate cancer has become increasingly important over time, as the incidence of prostate cancer has been on the rise and better screening techniques have emerged. The development of personalized systemic therapies highlights the unmet need for whole-body imaging. Prostate-specific membrane antigen (PSMA) PET, with its ease of performance and mechanism of localization to prostatic tumor cells, has now emerged as a preferred modality for diagnosis, staging, and treatment response assessment. In this context, PSMA PET can help in mapping the disease extent, both the skeletal and visceral spread, to plan targeted therapeutic approaches.
