Magnetic resonance imaging (MRI) has become an important tool in the assessment of fetal anomalies. Although ultrasound remains the modality of choice for screening, MRI offers several advantages that permit optimal characterization of anomalies in certain situations. Accurate recognition and characterization of fetal anomalies guides decisions about pregnancy management and coordination of postnatal care. This article will briefly review safety and practical aspects of fetal MRI. We will then provide a concise summary of the most common indications for fetal MRI, and discuss the differential diagnosis and role of MRI in assessment of fetal brain, head, neck, spine, and chest anomalies.
磁共振成像（MRI）已成为评估胎儿异常情况的重要工具。尽管超声仍是筛查的首选方式，但MRI具有一些优势，使其在某些情况下能够对异常情况进行最佳特征描述。准确识别和描述胎儿异常情况有助于指导妊娠管理决策以及产后护理的协调。本文将简要回顾胎儿MRI的安全性和实际应用方面。然后，我们将简要总结胎儿MRI最常见的适应证，并讨论MRI在评估胎儿脑、头、颈、脊柱和胸部异常中的鉴别诊断及作用。
