摘要
评估胎儿颅脑畸形是产前超声诊断的重点和难点.随着超声仪器分辨率和超声医师对中枢神经系统疾病认知水平的提高,以及神经系统超声方法学技术的进步,产前超声可见颅脑异常越来越多.但目前癫痫、智力低下及运动功能受损等胎儿期脑功能异常性临床表型仍为产前超声所不可见,有望通过先进的神经系统超声方法学评价脑沟回发育而间接进行推断.本文综合颅脑超声表现异常程度、结构或功能异常严重程度及预后就产前超声评估胎儿颅脑异常现状进行述评.
Abstract
Evaluation on fetal brain malformations is the key focus and challenge of prenatal ultrasound.With the improvement of ultrasound equipment resolution and sonographers'understanding of central nervous system disorders,as well as the advancement of neurological ultrasound methodology,more and more brain abnormalities were detected prenatally.But the clinical phenotypes of functional brain abnormalities during fetal period,such as epilepsy,intellectual disability and motor dysfunction,remained not visible by prenatal ultrasound,which is expected to be inferred indirectly by evaluating the development of brain sulci through advanced neurological ultrasound methodology.The status of prenatal ultrasound for evaluating fetal brain were reviewed based on prominence of ultrasonic features,severity of structural or functional abnormalities and prognosis in this article.
