The new PI-RADS version 2 classification (PI-RADS v2) was proposed together with the European Society of Urogenital Radiology (ESUR) and the American College of Radiology (ACR) in December 2014. In contrast to PI-RADS v1, the v2 regulate how to classify final PI-RADS score. for routine clinical use, test of the validity of v2, including its sensitivity and specificity for prostate cancer (PCa) detection should raise concerns, and literature of them less. So, the purpose of our study was to compare the diagnostic performance of v1 and v2 for the detection of PCa.
