This prospective phase II study assesses the accuracy of second generation prostate specific membrane antigen (PSMA) positron emission tomography (PET; utilizing 18F-PSMA-1007)) and multiparametric magnetic resonance imaging (MRI) for locoregional staging of clinically significant prostate cancer in men undergoing radical prostatectomy and bilateral pelvic lymph node dissection. The design will be a multicenter validating-paired cohort study using radical prostatectomy and pelvic lymph node dissection as the gold standard comparator. Each patient will undergo both 18F-PSMA-1007 PET and 3T MRI allowing comparison of each imaging modality within each subject. Furthermore, PET and MRI will be compared to standard-of-care imaging techniques (CT abdomen/pelvis and 99mTc-MDP Bone scan).
