The purpose of this article is to review gadolinium-based contrast agent (GBCA)-enhanced MRI applications in the genitourinary system. Nephrogenic systemic fibrosis is rare or nonexistent with standard dosing of group II GBCAs. Gadolinium retention, cost, and examination times are emerging considerations affecting GBCA use. GBCA is unnecessary to diagnose adrenal adenomas, simple cysts, and some Bosniak category II cysts; however, it is required to determine solid or septal renal mass enhancement. Biparametric prostate MRI requires high-quality and reproducible DWI; therefore, dynamic contrast-enhanced MRI remains valuable in selected prostate MRI examinations.
本文旨在综述钆基造影剂（GBCA）增强磁共振成像（MRI）在泌尿系统中的应用。使用标准剂量的II类GBCA时，肾源性系统性纤维化很少见或不存在。钆潴留、成本和检查时间是影响GBCA使用的新出现的考虑因素。诊断肾上腺腺瘤、单纯囊肿和一些博斯尼亚克II类囊肿时不需要使用GBCA；然而，确定实性或分隔性肾肿块的强化需要使用GBCA。双参数前列腺MRI需要高质量且可重复的扩散加权成像（DWI）；因此，动态对比增强MRI在某些选定的前列腺MRI检查中仍然很有价值。
