Multiparametric MRI has developed as a tool for prostate cancer lesion detection, characterization, staging, surveillance, and imaging of local recurrence. Given the disease frequency and the growing importance of imaging, as reliance on PSA declines, radiologists involved in prostate MRI imaging must become proficient with the fundamentals of multiparametric prostate MRI (T2WI, DWI, DCE-MRI, and MR spectroscopy). Interpretation and reporting must yield accuracy, consistency, and add value to clinical care. This review provides a primer to novices and trainees learning about multiparametric prostate MRI. MRI technique is presented along with the use of particular MRI sequences. Relevant prostate anatomy is outlined and imaging features of prostate cancer with staging are discussed. Finally structured reporting is introduced, and some limitations of prostate MRI are discussed.
多参数磁共振成像已发展成为一种用于前列腺癌病灶检测、特征描述、分期、监测及局部复发成像的工具。鉴于疾病的发病率以及成像的重要性日益增加，随着对前列腺特异性抗原（PSA）依赖程度的下降，从事前列腺磁共振成像的放射科医生必须精通多参数前列腺磁共振成像（T2加权成像、扩散加权成像、动态对比增强磁共振成像和磁共振波谱）的基本原理。解读和报告必须具备准确性、一致性，并为临床护理增添价值。本综述为初次接触及正在学习多参数前列腺磁共振成像的人员提供了一份入门指南。文中介绍了磁共振成像技术以及特定磁共振成像序列的应用。概述了相关的前列腺解剖结构，并讨论了前列腺癌的成像特征及分期。最后介绍了结构化报告，并讨论了前列腺磁共振成像的一些局限性。
