Version 2 of the Prostate Imaging and Reporting and Data System (PI-RADS) was developed to help in the detection, location, and characterization of prostate cancer with magnetic resonance imaging (MRI). Its recommendations for standardizing image acquisition parameters aims to reduce variability in the interpretation of MRI studies of the prostate; this approach, together with structured reporting, has the added value of improving communication among radiologists and between radiologists and urologists. This article aims to explain the PI-RADS v2 classification in a simple way, using illustrative images for each of the categories, as well as to recommend the use of a standard technique that helps ensure the reproducibility of multiparametric MRI.
The PI-RADS v2 is simple to appy when reading multiparametric MRI studies of the prostate. It is important for radiologists doing prostate imaging to use the PI-RADS v2 in daily practice to write clear and concise reports that improve communication between radiologists and urologists.
前列腺影像报告和数据系统（PI-RADS）第2版的开发旨在借助磁共振成像（MRI）辅助前列腺癌的检测、定位及特征描述。其对图像采集参数进行标准化的建议旨在减少前列腺MRI研究解读中的变异性；这种方法与结构化报告相结合，具有改善放射科医生之间以及放射科医生与泌尿科医生之间沟通的附加价值。本文旨在以简单的方式解释PI-RADS v2分类，为每个类别使用说明性图像，并推荐使用有助于确保多参数MRI可重复性的标准技术。
在解读前列腺多参数MRI研究时，PI-RADS v2易于应用。对于进行前列腺成像的放射科医生而言，在日常实践中使用PI-RADS v2来撰写清晰简洁的报告以改善放射科医生与泌尿科医生之间的沟通非常重要。
