Although prostate cancer MR imaging (MRI) has advanced as a result of the improvement in hardware technology and the development of software for clinical use, including multi-parametric MRI(MP-MRI), which has been recognized as a useful tool, the ability of MP-MRI to diagnose prostate cancer has not been improved dramatically. To standardize the reporting system of MP-MRI of the prostate, the European Society of Urogenital Radiology published a prostate imaging reporting and data system (PI-RADS) in 2012. Objective evaluation is very important, but inter-reader agreement of PI-RADS scoring is not so high. In 2014, it was revised as the PI-RADS version 2. This new system is being assessed now. Prostate MRI has great potential to optimize clinical practice in patients with this type of cancer, not only in terms of cancer detection but also cancer localization before biopsy or operation, monitoring active surveillance patients, etc.
