The purposes of this study were to assess correlation apparent diffusion coefficient (ADC) and normalized ADC (ratio tumor nontumor tissue) with the Prostate Imaging Reporting Data System version 2 (PI-RADSv2) updated International Society Urological Pathology (ISUP) categories determine how optimally use metrics for objective assistance in categorizing lesions within PI-RADSv2 guidelines.
