【摘要】 目的 探讨头颅计算机体层摄影术(CT)及B超检查对新生儿缺氧缺血性脑病（HIE ）的诊断价值以及临床意义。方法 随机选择94例新生儿,分别行头颅CT及B 超检查，并对照临床诊断,比较两种检查结果及其与临床诊断的符合情况。结果 头颅CT及B超检查对轻度HIE 的诊断与临床诊断符合率为39%及83%；对中度HIE的诊断与临床诊断符合率为43%及100%；而对重度HIE的诊断，两种检查方法的结果无差异，且与临床诊断一致。此外，CT诊断颅内出血9例，而B超仅发现颅内出血4例。结论 B超对轻、中度HIE的诊断与临床诊断的符合率高于CT，然而CT对颅内出血的诊断优于B超。

【Abstract】 Objective To investigate diagnostic value of computed tomography (CT) and ultrasonography for detecting hypoxic-ischemic encephalopathy (HIE) and to evaluate their clinical implications. Methods 94 neonates were examined with CT and ultrasonography, respectively, for detecting HIE and the results were compared to clinical investigation. Results Significant difference (P<0.01) was found for diagnosis of mild and moderate HIE by CT and ultrasonography. Compared with clinical diagnosis, the agreement rates of ultrasonography and CT were 83% and 39% (P<0.01) for mild HIE, and 100% and 43% (P<0.01) for moderate HIE respectively. There was no difference for detecting severe HIE among clinical diagnosis, CT and ultrasonography. Additionally, 9 cases with intracranial hemorrhage were detected by CT in which only 3 cases were found by ultrasonography. Conclusions Compared with clinical finding for diagnosis of mild and moderate HIE, the agreement rate of ultrasonography is higher than that of CT. However, CT is more sensitive to detect intracranial hemorrhage than ultrasonography.

新生儿缺氧缺血性脑病（hypoxia ischemic ence- phyalopthy，HIE）系指围产期窒息所致的脑部缺氧缺血性损伤，是导致新生儿死亡以及远期致残的主要原因。如何早期诊断，对指导临床治疗、正确评估预后有重要意义。为探讨计算机体层摄影术(CT)及B超检查对HIE的诊断价值，我们分析了[1] [2] [3] 下一页
