Prostate Imaging Reporting and Data System (PI-RADS), Version 2: A Critical Look

Abstract

PI-RADS v2 offers clear improvements to its earlier version and will greatly benefit the prostate MRI community. Nonetheless, caution remains on the basis of early user experience, and potential ambiguities and gaps of PI-RADS v2 are noted. Continued data-driven clarification and refinement of the guidelines will be invaluable for PI-RADS v2 to achieve its goal of improving patient care.
