Abstract
This review presents a practical approach to imaging the fetal brain by MRI. Herein, we demonstrate how to measure brain structures and fluid spaces, and discuss the importance of comparing measurements to normative biometric references at a corresponding gestational age. We present some common imaging dilemmas of the technical aspects of fetal MRI with regard to typical regions of abnormality including the cerebrum, the ventricular system, and the posterior fossa, and discuss how to resolve them.
摘要
这篇综述介绍了一种通过 MRI 对胎儿大脑进行成像的实用方法。在这里，我们展示了如何测量脑结构和脑脊液腔，并讨论了将测量值与相应胎龄的正常生物参考值进行比较的重要性。我们提出了一些关于胎儿 MRI 技术方面的常见成像难题，包括大脑、脑室系统和后颅窝等典型异常区域，并讨论了如何解决这些问题。
