摘　　要：磁共振成像(magnetic resonance imaging,MRI)技术不断发展,其越来越多的运用于胎脑发育的评估之中。胎脑发育是一个动态、复杂的过程,其结构在MRI上可清晰地表现出来。只有熟知胎脑发育的正常MRI表现,才能对发育异常做出准确判断。文中主要对胎脑的幕上脑实质、脑沟形成、脑室、胼胝体、灰质核团、颅后窝结构和髓鞘的发育及它们在MRI上的正常表现做一综述。MRI technology is increasingly used for the evaluation of fetal brain development which is a dynamic and complicated process.The structure of the fetal brain can be clearly displayed by MRI.The understanding of MRI appearance of the normal fetal brain is essential for correct identification of its developmental abnormalities.This article focuses on some key aspects of fetal brain development including supratentorial parenchyma,sulcation,ventricles,corpus callosum,deep gray nuclei,posterior fossa structures and myelination,as well as their normal appearance in MRI.
