PI-RADS (Prostate Imaging-Reporting and Data System) is a standardized scoring system for prostate MRI that has transformed clinical trials through consistent assessment methods. With proven sensitivity of 86.2% and specificity of 84.7% at PI-RADS score ≥ 4, it enables reliable multi-center research and improved patient stratification in clinical trials.
Evolution of PI-RADS in Medical Imaging
The standardization of prostate imaging has undergone significant evolution since its inception. This journey reflects the collaborative effort of radiologists, researchers, and clinicians worldwide to create a unified approach to prostate cancer detection. The system's development has been marked by continuous refinement based on clinical evidence and research outcomes.
A comprehensive review in Radiology confirms:
"PI-RADS has evolved through systematic updates, from its introduction in 2012 to version 2.0 in 2015, and the current version 2.1 released in 2019."
