Abstract

Fetal MR now plays an important role in the clinical work-up of pregnant females. It is performed mainly at 1.5 T. However, the desire to obtain a more precise fetal depiction or the fact that some institutions have access only to a 3.0 T scanner has resulted in a growing interest in performing fetal MR at 3.0 T. The aim of this article was to provide a reference for the use of 3.0 T MRI as a prenatal diagnostic method.

摘要

胎儿磁共振成像目前在孕妇的临床检查中发挥着重要作用。它主要在1.5T的磁场强度下进行。然而,出于获得更精确胎儿图像的需求,或者一些机构仅能使用3.0T扫描仪这一事实,使得人们对在3.0T磁场强度下进行胎儿磁共振成像的兴趣日益浓厚。本文的目的是为将3.0T磁共振成像用作产前诊断方法提供参考。
