PI-RADS Version 2.1 makes several minor modifications aimed at addressing these issues and simplifying the scoring system without changing the overall framework for acquisition or interpretation using the principles of the dominant sequence paradigm. Formal investigations of the Interobserver agreement of the PI-RADS version 2.1 scoring system are critical to confirm that it is attaining its primary aim of standardization.
