In this article we take a critical look at the key changes of the newest edition of the Prostate Imaging Reporting and Data System (PI-RADS) version 2.1 (v2.1) and indicate future directions for further development of the system.
PI-RADS v2.1 addresses some of the shortcomings of its widely embraced precursor version 2, largely to simplify interpretation and improve interobserver agreement without changing the fundamental acquisition and scoring guidelines. Biparametric MRI is acknowledged in the newest version, but multiparametric MRI including dynamic contrast-enhanced imaging is still recommended for most scenarios. Management recommendations and guidance on evaluation of follow-up MRI's are still not included in the system.
在本文中，我们批判性地审视了最新版前列腺影像报告和数据系统（PI-RADS）第 2.1 版（v2.1）的主要变化，并指出了该系统进一步发展的未来方向。
PI-RADS v2.1 解决了其广受欢迎的前身版本 2 的一些缺点，主要是通过简化解释和提高观察者间一致性，而不改变基本的采集和评分准则。新版本承认了双参数 MRI，但仍推荐在大多数情况下使用多参数 MRI 包括动态对比增强成像。该系统仍然不包括管理建议和随访 MRI 评估的指导。
