Abstract：
This article provides the readers with practical guidance on how to perform fetal MR imaging, including technical considerations such as scanner field strength and use of appropriate radiofrequency receive coils, and summarizes the role, strengths, and limitations of the various MR imaging sequences. The authors review the various factors to consider in scan preparation, including study indication, timing, maternal preparation, and the creation of an institutional fetal imaging protocol. Additional factors that go into scan optimization during acquisition including prioritizing maternal comfort and ways to troubleshoot various artifacts that maybe encountered in fetal imaging are discussed.
摘要：
本文为读者提供了如何进行胎儿MR成像的实践指导，包括扫描仪场强和使用适当的射频接收线圈等技术考虑因素，并总结了作用，优势,以及各种MR成像序列的局限性。作者回顾了扫描准备中要考虑的各种因素，包括研究适应症，定时,产妇准备,以及机构胎儿成像协议的建立。讨论了在采集期间进行扫描优化的其他因素，包括优先考虑产妇的舒适度以及对胎儿成像中可能遇到的各种伪影进行故障排除的方法。
