In the last few years fetal magnetic resonance imaging (MRI) has been proposed as a second level technique in the evaluation of fetal brain anomalies. It has been demonstrated that MRI is highly accurate in illustrating the morphologic changes of developing brain and fetal brain abnormalities being a useful procedure when ultrasonography is inconclusive or doubtful. Starting from the 19-20 weeks gestational age (GA), MRI can reliably depict fetal brain anatomy and locating pathology, offering a robust and reliable tool in the assessment of fetal CNS diseases. In this review both in vivo MRI quantitative and qualitative data about fetal cerebellar development are presented and compared with ultrasonography data. Fetal cerebellar development is gradual, steady, and largely comparable to the development of the supratentorial brain. Archicerebellar (flocculo-nodular lobe) and paleocerebellar (vermis) structures develop first, whereas neocerebellum (cerebellar hemispheres) develop slowly and largely after birth.

在过去的几年中,胎儿磁共振成像 (MRI) 已被提议作为评估胎儿大脑异常的第二级技术。已经证明,当超声检查不确定或可疑时,MRI在说明发育中的大脑和胎儿大脑异常的形态变化方面非常准确,这是一种有用的方法。从19-20周的胎龄 (GA) 开始,MRI可以可靠地描述胎儿的大脑解剖结构和定位病理,为评估胎儿中枢神经系统疾病提供了可靠可靠的工具。在这篇综述中,介绍了有关胎儿小脑发育的体内MRI定量和定性数据,并将其与超声检查数据进行了比较。胎儿小脑的发育是渐进的,稳定的,并且在很大程度上与幕上大脑的发育相当。小脑 (小脑结节叶) 和古小脑 (ver) 结构首先发育,而新脑 (小脑半球) 在出生后缓慢且大部分发育。
