The prostate imaging reporting and data system (PI-RADS) is a standardized reporting system for multiparametric MRI in treatment-naive patients to evaluate for suspected prostate cancer. The PI-RADS category corresponds to a likelihood of clinically signficant cancer (1=highly unlikely, 2=unlikely, 3=indeterminate, 4=likely, 5=highly likely).
