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.
