【摘要 】 目的 为比较正常新生儿和缺氧缺血性脑病(HIE)患儿脑白质密度CT值,并观察脑白质低密度形态改变与临床分度的关系。 方法 30例正常新生儿及81例HIE患儿作为研究对象。 结果 (1)30例正常新生儿脑白质CT值为18~28 Hu,HIE36例为5~19Hu,χ2 =62.1,P<0.01。(2)45例HIE患儿中,轻度、中度及重度HIE其脑白质形态改变的发生率分别为35.7%,90%及100%。17例中、重度HIE中有6例CT值均大于18Hu,但均有中到重度的形态改变。 结论 只有将白质低密度的范围、程度(CT值)及脑白质低密度形态改变三者结合起来分析,CT脑损害的诊断才能较客观地确立。

【 Abstract 】 Objective To compare CT value of cerebralwhite matter in normal and HIE neonates and to observe the relation between shape of whitematter hypodensity and clinical feature of HIE. Methods Thirty normal neonates and 81 HIE neonates were studiedprospectively. Results (1) CT value of white matter in30 normal and 36 HIE neonates were 18~ 28 Hu and 5~ 19 Hu respectively (χ 2 =61.1, P=<0.01) ......
