Magnetic resonance (MR) imaging is an important imaging technique in the evaluation of scrotal masses, providing a useful adjunct to ultrasonography (US). Although US is the modality of choice for initial evaluation of scrotal pathologic conditions because of its wide availability, low cost, and high sensitivity for detection of testicular and paratesticular disease processes, US findings may occasionally be inconclusive. MR imaging may provide additional information in these cases, often affecting patient management. This article reviews and illustrates the MR imaging features of solid extratesticular and intratesticular benign and malignant scrotal tumors, as well as nonneoplastic lesions that can mimic neoplasia. Normal scrotal MR anatomic features and optimal MR imaging technique are also presented.
磁共振（MR）成像是评估阴囊肿块的重要成像技术，为超声（US）提供了有用的补充。虽然 US 由于其广泛的可用性、低成本和对睾丸和附属性疾病过程的高灵敏度，是阴囊病理情况初始评估的首选方式，但 US 结果偶尔可能不明确。在这些情况下，MR 成像可能会提供额外的信息，通常会影响患者的管理。本文回顾并说明了实体性和睾丸内阴囊良性和恶性肿瘤以及可模拟肿瘤的非肿瘤性病变的 MR 成像特征。还介绍了正常阴囊的 MR 解剖特征和最佳 MR 成像技术。
