[摘要] 目的 探讨常规头颅CT扫描加薄层扫描在新生儿缺氧缺血性脑病诊断中的应用价值。方法 对60例临床诊断为新生儿缺氧缺血性脑病患儿行常规头颅CT扫描，对兴趣区加薄层扫描，观察常规头颅扫描结合局部薄层扫描条件下颅内脑组织密度变化情况。结果 40例新生儿缺氧缺血性脑病患儿平扫时，脑叶低密度区显示不明显。18例小脑幕缘高密度影显示模糊。2例单纯脑沟可疑高密度影，加薄扫后病灶清晰显示。 结论 常规头颅CT扫描结合对脑叶低密度区及高密度区显示模糊的层面进行薄层扫描，能清楚显示常规头颅扫描未能显示或显示不清的病灶，特别是对脑回、脑沟显示更清晰，能够观察微细的脑组织密度变化，对新生儿缺氧缺血性脑病的诊断起着重要作用。[关键词] 新生儿；缺氧缺血性脑病；薄层扫描

[Abstract] Objective To analyze the application value between head routine CT scanning and shallow scanning in diagnosis of neonatal hypoxic ischemic encephalopathy. Methods 60 neonates with clinically proved hypoxic ischemic encephalopathy underwent head routine CT scanning and shallow scanning and then observed the results of head routine CT scanning and partial shallow scanning,found out the condition of the tissue density in the head. Results 40 neonates under went routine CT scanning.The result was not very clear in low density lesions,18 neonates were indistinct in the high density lesions,2 neonates underwent CT scanning and shallow scanning in high density lesions.The focus was very clear.Conclusion Routine CT scanning and shallow scanning of the tissue density in low and high indistinct density lesions.Show the focus more clearly than simply routine CT scanning especially in the lesions of circuit and groove.Shallow scanning can observe the infinitely change in the lesions of tissue density.Shallow scanning plays an important part in diagnosis of neonatal hypoxic ischemic encephalopathy. ......
