Prostate cancer is a significant health concern in men that is typically investigated by using serum prostate specific antigen and systematic transrectal ultrasound-guided prostate biopsy. Recently, two large prospective multicentre studies have demonstrated that using multiparametric magnetic resonance imaging to triage men with high serum prostate specific antigen levels was a more cost-effective strategy for diagnosing clinically significant cancer, compared with the traditional management pathway. The Prostate Imaging Reporting and Data System (PI-RADS), currently in its second version, was developed to provide technical guidelines on image acquisition and a structured system for reporting of multiparametric magnetic resonance imaging examinations. In this pictorial essay, we will provide an overview of the general technical considerations and guidelines on image interpretation and reporting using PI-RADS version 2, before illustrating the common pitfalls radiologists encounter when applying this system.

應用第二版前列腺成像報告及數據系統時的常見陷阱：圖像綜述
袁子祐、曹子文、洪曉義
前列腺癌是男性的重要健康問題，一般以血清前列腺特異性抗原和系統經直腸超聲引導的前列腺活檢進行檢查。最近兩項大型前瞻性多中心研究表明，與傳統治療方法相比，使用多參數磁共振成像為血清前列腺特異性抗原高水平男性患者進行分類，對於診斷臨床顯著的前列腺癌症更具成本效益。前列腺成像報告及數據系統（PI-RADS）目前已發展至第二版，提供圖像採集技術指南以及報告多參數磁共振成像檢查的結構化系統。本文概述使用PI-RADS第二版的圖像解釋及一般技術考慮和指南，然後說明放射科醫生在應用該系統時遇到的常見陷阱。
