【摘 要】 目的 讨论新生儿缺氧缺血性脑病的CT诊断和随访价值。 方法 对56例缺氧缺血性脑病患儿行头部CT平扫，分析CT征象。 结果 12例CT诊断为轻度HIE，表现为大脑实质内有斑片状低密度灶，范围≤2个脑叶;26例诊断为中度HIE，病灶分布超过2个脑叶，其中10例合并颅内出血。18例诊断为重度HIE，大脑半球呈弥漫性低密度，脑室、脑池变窄，其中8例合并颅内出血。随访32例，7例恢复正常，12例脑萎缩，5例脑积水，3例遗留脑软化灶，5例双额少量硬膜下积液。 结论 CT能准确诊断HIE，还可用于随访观察其后遗症。

    【Abstract】 Objective To evaluate CT diagnosis and follow-up study of hypoxic-ischemic encephalopathy in neonates.Methods The CT features of56cases of hypoxic-ischemic encephalopathy in neonates were studied.Results Mild degree of en-cephalopathy was found in12cases showing a size not exceeding2lobes.The pathological changes were moderately advanced in26cases.The size of the diseased patch exceeded2lobes.There was subarachnoid hemorrhage in10out of the26cases.Severe manifestations of encephalopathy occurred in18cases.Low-density patch extended over the cerebral hemisphere and the ventri-cle and cisterna were narrowed.Intracerebral bleeding occurred in8out of the18cases.Followup observation with CT revealed recovery to normal in7cases ......
