Abstract

This is a report of the CAT-scan and MRI characteristics in 14 patients with anomalies of neuronal migration. There were 3 cases of heterotopia of the gray matter, 2 cases of agyria, 3 cases of pachygyria, 2 cases of schizencephaly and 4 cases of hemimegalencephaly. The primary advantages of MRI in comparison with CAT-scanning, are better contrast between the white and gray matter; better delineation of the cerebral cortex and the possibility of direct mutiplanar imaging. NMRI will become the investigation of choice in children with epilepsy or psychomotor retardation.

摘要

这是一份关于14例神经元迁移异常患者的计算机断层扫描（CAT）和磁共振成像（MRI）特征的报告。其中有3例灰质异位症、2例无脑回畸形、3例巨脑回畸形、2例脑裂畸形和4例半侧巨脑症。与CAT扫描相比，MRI的主要优势在于白质和灰质之间的对比度更好；能更清晰地勾勒出大脑皮层，并且可以进行直接多平面成像。MRI将成为癫痫或精神运动发育迟缓儿童的首选检查方法。
