| 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(HIE)患儿颅脑CT影像特点。方法128例正常新生儿和332例HIE患儿行颅脑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值范围27～39HU,白质密度CT值范围20～28HU;HIE患儿脑白质CT值范围:轻度17～19.9HU,中度14～16.9HU,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。

| Abstract: | Objective To study the CT features and its correlation of normal neonates and neonatal hypoxic-ischemic encephalopathy(HIE).Methods 128 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 332 cases of neonatal HIE.Results The CT value of normal neonates were ranging from 27 to 39 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. |
