This review addresses specific questions regarding performance and utility of fetal MR. The specific issues addressed are (1) physician qualifications; (2) MR safety; (3) access to fetal MR; (4) timing of MRI in pregnancy; (5) repeat exams; and (6) when MRI is most effective for prenatal diagnosis. Fetal MRI is a problem-solving tool used for specific indications that are driven by ultrasound or at times by family history. Fetal MR should always be performed with knowledge of the sonographic findings from prior targeted scan. The best evidence for utility of MR is in assessment of CNS anomalies and assessment of the fetus with airway obstruction requiring decisions regarding mode of therapy. The type of information provided by MR can profoundly impact patient counseling and management. We recommend a team approach including specialists in obstetric imaging, fetal MRI, and postnatal care in interpreting MR so that the best information can be given to the pregnant patient.
这篇综述探讨了胎儿磁共振成像（MRI）的性能和实用性的具体问题。具体涉及的问题包括：（1）医师资质；（2）磁共振成像安全性；（3）胎儿 MRI 的应用；（4）孕期 MRI 检查的时机；（5）重复检查；（6）MRI 对产前诊断最有效的情况。胎儿 MRI 是一种针对特定情况的解决问题的工具，这些情况是由超声或家族史驱动的。胎儿 MRI 应始终在了解先前靶向扫描的超声结果的基础上进行。磁共振成像的实用性的最佳证据是在评估中枢神经系统异常和评估气道阻塞的胎儿方面，这需要决定治疗方式。磁共振成像提供的信息类型可以深刻影响患者咨询和管理。我们建议采用团队方法，包括产科影像学、胎儿 MRI 和产后护理方面的专家，以解读磁共振成像结果，从而为孕妇提供最佳信息。
