前列腺的多参数MRI （mpMRI）已经发展成为前列腺癌诊断、风险分层、分期和靶向治疗的一个组成部分。然而，在mpMRI上存在前列腺癌的解剖和组织学模拟。mpMRI上类似前列腺癌的解剖特征包括前纤维肌间质、正常中央区、前列腺周围静脉丛和增厚的手术包膜（过渡区假包膜）。良性病变如活检后出血、前列腺炎或炎症、局灶性前列腺萎缩、良性前列腺增生结节和前列腺钙化也可以在mpMRI上模拟前列腺癌。技术挑战和其他缺陷，如图像失真、运动伪影和直肠内线圈放置也会限制mpMRI的疗效。了解前列腺解剖、病变位置及其在不同序列上的成像特征，并熟悉常见的陷阱对解释mpMRI的放射科医生至关重要。因此，本文回顾了mpMRI上的陷阱（解剖结构和技术挑战）和良性病变或异常可能模仿前列腺癌，以及如何解释它们。
Multiparametric MRI (mpMRI) of the prostate has evolved to be an integral component for the diagnosis, risk stratification, staging, and targeting of prostate cancer. However, anatomic and histologic mimics of prostate cancer on mpMRI exist. Anatomic feature that mimic prostate cancer on mpMRI include anterior fibromuscular stroma, normal central zone, periprostatic venous plexus, and thickened surgical capsule (transition zone pseudocapsule). Benign conditions such as post-biopsy hemorrhage, prostatitis or inflammation, focal prostate atrophy, benign prostatic hyperplasia nodules, and prostatic calcifications can also mimic prostate cancer on mpMRI. Technical challenges and other pitfalls such as image distortion, motion artifacts, and endorectal coil placements can also limit the efficacy of mpMRI. Knowledge of prostate anatomy, location of the lesion and its imaging features on different sequences, and being familiar with the common pitfalls are critical for the radiologists who interpret mpMRI. Therefore, this article reviews the pitfalls (anatomic structures and technical challenges) and benign lesions or abnormalities that may mimic prostate cancer on mpMRI and how to interpret them.
