Prostate-specific membrane antigen PET/computed tomography for staging prostate cancer

Abstract

PURPOSE OF REVIEW: Molecular imaging with PET/CT targeting the prostate-specific membrane antigen (PSMA) receptor is increasingly utilized in men with prostate cancer (PCa), with clinical indications now expanding beyond biochemical recurrence. PSMA PET/CT often detects sub-centimetre size pathologic nodes and low-volume bone marrow disease that are occult on conventional imaging when the lesion does not cause sclerosis or osteoblastic reaction in surrounding bone. This review focuses on recent evidence for PSMA PET/CT in initial disease staging. RECENT FINDINGS: Several recent studies including a large randomized trial have evaluated the clinical impact of PSMA PET/CT in initial staging of ..
