The main goal of this phase II clinical trial is to define a novel approach of staging prostate cancer (PCa) patients by using a fully integrated positron emission tomography/ magnetic resonance imaging (PET/MRI) system with 68Ga-prostate specifica membrane antigen (PSMA) and 68Ga-RM2 (bombesin antagonist).
50 patients with biopsy proven PCa will be studied by PET/MRI with 68Ga-PSMA and with 68Ga-RM2 and then will undergo prostatectomy and pelvic lymphadenectomy.
