What is PI-RADS 2.1?
PI-RADS (Prostate Imaging Reporting and Data System) version 2.1 is an internationally recognized standardized reporting system developed jointly by the American College of Radiology (ACR) and European Society of Urogenital Radiology (ESUR). It provides a structured framework for radiologists to interpret prostate multiparametric MRI (mpMRI) and assess the likelihood of clinically significant prostate cancer.
This calculator helps healthcare professionals systematically evaluate prostate lesions using diffusion-weighted imaging (DWI), T2-weighted imaging (T2W), and dynamic contrast-enhanced (DCE) sequences to generate a PI-RADS score that predicts cancer risk.
This calculator is based upon the American College of Radiology (ACR) PI-RADS 2.1 classification but is not officially endorsed by the ACR.
