Previously presented Prostate Imaging Reporting and Data System version 2 (PI-RADS v2) system was developed on the basis of consensus that was achieved by the results of published studies containing expert and analytical conclusions. Numerous studies on PI-RADS v2, not only confirmed the importance of a unified system in the diagnosis of prostate cancer, but also revealed a number of limitations. In order to eliminate flaws of PI-RADS v2, a number of potential solutions were proposed.
