Urinary system birth defects represent the abnormality most often detected in prenatal studies, accounting for 30% to 50% of all structural anomalies present at birth. The most common disorders are urinary tract dilation, developmental variants, cystic kidney diseases, kidney tumors, and bladder defects. These anomalies can present in isolation or in association with various syndromes. They are normally evaluated with sonography, and the use of magnetic resonance imaging (MRI) is considered only in inconclusive cases. In this article, we show the potential of fetal MRI as a technique to complement sonography in the study of fetal urinary system anomalies. We show the additional information that MRI can provide in each entity, especially in the evaluation of kidney function through diffusion-weighted sequences.
泌尿系统出生缺陷是产前研究中最常检测到的异常情况，占出生时所有结构异常的30%至50%。最常见的病症是尿路扩张、发育变异、多囊肾病、肾肿瘤和膀胱缺陷。这些异常情况可单独出现或与各种综合征相关联。通常通过超声检查对其进行评估，仅在诊断不明确的情况下才考虑使用磁共振成像（MRI）。在本文中，我们展示了胎儿MRI作为一种在胎儿泌尿系统异常研究中补充超声检查的技术的潜力。我们展示了MRI在每个实体中可以提供的额外信息，特别是通过扩散加权序列对肾功能的评估。
