摘要
收集 53例临床上有宫内窒息史和 8例无宫内窒息史、产伤史的足月新生儿 ,进行临床分度和CT分度对照。在临床与CT不符合的新生儿中 ,CT分度重于临床分度 14例 ,均为轻度新生儿缺氧缺血性脑病 (HIE) ,占其中 4 1 2 %。CT诊断蛛网膜下腔出血 (SAH) 38例 ,其中 14例为正常硬膜窦影 ,假阳性率为 36 8%。CT分度轻于临床分度 8例 ,其中 4例为中度和重度HIE。造成CT与临床诊断不符合的主要原因是对新生儿正常影像认识不足 ,包括生理性低密度和上矢状窦高密度影。此外 ,尚与个体差异 ,出生距CT扫描时间过短有关。
To evaluate the CT diagnosis of hypoxia-ischemic encephalopathy (HIE) in the newborn, clinical and CT grade of 53 cases of newborn with asphyxia in uretus and 8 cases without aspyxia and birth injury were analyzed. The results suggest that disagreements of clinical and CT grade are often in the HIE of the newborn. It is very important for improving CT diagnosis of HIE in the newborn to recognize the normal newborn's CT findings.
