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。Objective To investigate diagnostic value of computed tomography (CT) and ultrasonography for detecting hypoxicischemic 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.
