This article is the first portion of a two-part review that illustrates the normal appearance of the cerebellum and posterior fossa on prenatal ultrasound and MRI and on postnatal diagnostic imaging studies. Classification and terminology of posterior fossa abnormalities in the literature are confusing due to evolution of concepts and sometimes lack of consensus. Accurate classification of posterior fossa anomalies is important for predicting fetal outcome and for appropriate counseling. In Part 1 of this review, prenatal and postnatal imaging techniques for assessing the posterior fossa will be discussed, followed by a discussion of how cerebellar malformations may be classified.
本文是一篇分两部分的综述的第一部分，阐述了产前超声、磁共振成像（MRI）以及产后诊断性影像学检查中小脑和后颅窝的正常表现。由于概念的演变以及有时缺乏共识，文献中后颅窝异常的分类和术语令人困惑。准确分类后颅窝异常对于预测胎儿预后和进行适当的咨询很重要。在本综述的第一部分，将讨论评估后颅窝的产前和产后成像技术，随后讨论小脑畸形的分类方法。
