目的：提高新生儿缺氧缺血性脑病（HIE）的CT早期诊断丰。材料与方法：收集HIE66例，首次CT检查时间在2小时至13天，其中14例在7天至12天做了复查，1例在4月和13月后做了复查。结果：①所有病例脑内均出现了低密度灶（＜18Hu）。②蛛网膜下腔出血（SAH）的发生率为38／66。③低密度灶出现的越广泛，SAH的发生率越高。④临床上有窒息和抽搐史的新生儿，其低密度区的范围大，SAH的发生率高。结论：CT是目前诊断HIE的最佳检查方法。
Objective: To improve the early diagnosis of neonatal hypoxic-ischemic encephalopathy (HIE) Feng. MATERIALS AND METHODS: Sixty-six cases of HIE were collected. The first CT scan was performed between 2 hours and 13 days. Of them, 14 cases were reviewed between 7 days and 12 days and 1 case was reviewed in April and 13 months. Results: ① All cases showed low density lesions (<18 Hu) in the brain. ② The incidence of subarachnoid hemorrhage (SAH) was 38/66. ③ low-density lesions appear more widely, the higher the incidence of SAH. ④ clinically asphyxiated and convulsive history of newborns, the scope of its low-density area, the high incidence of SAH. Conclusion: CT is the best method for the diagnosis of HIE.
