目的研究核磁共振成像(MRI)对于新生儿缺氧缺血性脑病(HIE)的早期诊断价值。方法回顾分析MRI室检查的73例足月HIE患儿的临床资料,分析其MRI系列影像学表现。结果 MRI显示HIE患儿的早期影像学特征有:47例(64.38%)脑水肿(44例为局限性脑水肿),42例(57.53%)蛛网膜下隙出血,7例(9.59%)脑室内出血,5例(6.85%)脑实质出血,1例(1.37%)大面积脑梗死。结论 HIE早期具有多种MRI表现,早期进行MRI检查能够反映患儿的脑损害程度及范围,为临床诊断及治疗提供参考。
Objective To study the early diagnosis of neonatal hypoxic-ischemic encephalopathy (HIE) by magnetic resonance imaging (MRI). Methods The clinical data of 73 full-term HIE children undergoing MRI examination were retrospectively analyzed. MRI features of the MRI findings were analyzed. Results MRI showed that the early imaging features of HIE were 47 cases (64.38%) of cerebral edema (44 cases of localized cerebral edema), 42 cases (57.53%) of subarachnoid hemorrhage and 7 cases (9.59%) of ventricles Internal bleeding, 5 cases (6.85%) brain parenchymal hemorrhage, 1 case (1.37%) large area cerebral infarction. Conclusions There are many MRI manifestations in early stage of HIE. Early MRI can reflect the extent and range of brain damage in children and provide reference for clinical diagnosis and treatment.
