【摘要】 目的 :探讨出生周内正常新生儿与新生儿缺氧缺血性脑病患儿 (HIE)颅脑CT影像特点。材料和方法 :6 4例正常新生儿和 16 6例HIE患者行颅脑CT扫描 ,取特定的扫描层面及位置 ,双侧对称检测脑实质密度CT值。结果 :正常新生儿灰质密度CT值 2 7～ 39Hu ,白质密度 2 0～ 2 8Hu ;HIE轻度CT值 17～ 2 0Hu ,中度 14～ 17Hu ,重度 14Hu以下。结论 :出生周内正常新生儿与HIE患儿颅脑CT值测量指标对HIECT诊断具有重要意义更多还原

【Abstract】 Purpose: To study the CT features of normal neonates and neonatal hypoxia ischemic encephalopthy (HIE). Materials and Methods: 64 cases of normal neonate brains were scanned, the CT value arrangement was got by measuring CT value of bilateral cerebral parenchyma of related slices. On this basis, a quantitative classification criteria was made for 166 cases of neonatal HIE. Results: The CT value of normal neonates were ranging from 26 to 38 Hu for cerebral cortex and from 20 to 28 Hu for cerebral medulla. Neonates with HIE could be classified into three degrees according to CT value (17～19 9 Hu for gentle degree, 14～16.9 Hu for moderate degree and below 14 Hu for severe degree). Conclusion: The measuring CT value of cerebral cortex and medulla for normal neonates and neonatal HIE can play a significant role in clinical diagnosis of HIE.更多还原
