摘要/Abstract

摘要：利用螺旋CT通过66例正常新生儿和71例HIE患儿的颅脑CT扫描影像学数据统计学处理结果表明：正常新生儿脑白质密度偏低，CT值19.0~28.0 Hu,其中95.4%最低值为20 Hu，脑白质边缘多呈“枫叶”状，脑灰质CT值27.6~39.0 Hu；HIE脑白质低密度灶绝大部分CT值小于17.0 Hu，低密度灶边缘表现为“花瓣”状.说明CT诊断对HIE的早期诊断，协助制定治疗方案有较高价值，依据低密度脑水肿是否伴有脑室改变及颅内出血，进行CT型有许多优点.

Abstract: CT images of 66 normal neonates and 71 neonates with HIE were analyzed statisctically.The results showed that in normal neonates the alba density was slightly low with CT values of 19.0~ 28.0 Hu and the margin of it showed the "maple "sign. The lowest values of alba in 95.4%(63/66)normal neonates were 20Hu. CT values of normal ectocinarea were 27.6~39.0 Hu. Most CT values of low density leisions of alba with HIE were lower than 17Hu.The margins of them showed "petal" sign.The results demenstrated that CT was more valuable for early diagnosis of HIE and helpful for protocle making.Moreover,CT grade according to cerebral edema with or without cerebral ventricle changes or intracalvalium haemorrhage has more advantages.
