新生儿缺氧缺血性脑病的MRI诊断

MRI diagnosis of neonatal hypoxia-ischemia encephalopathy

目的探讨MRI对新生儿缺氧缺血性脑病的诊断价值。方法对42例临床诊断为缺氧缺血性脑病的新生儿行MRI检查,并对其MRI表现进行分析。结果所有患儿均有不同程度的脑损害。MRI表现:轻度HIE 15例(35.7%),中度HIE 19例(45.2%),重度HIE 8例(19.5%)。其中,蛛网膜下腔出血17例,脑实质内出血4例,脑室出血2例。结论MRI对新生儿HIE的诊断尤其对早期诊断具有重要价值。

Objective To investigate the value of MRI in the diagnosis of hypoxia-ischemia encephalopathy （HIE）. Methods MRI was performed in 42 neonates with hypoxia-ischemia encephalopathy. All findings were analyzed. Results All patients had different brain damage. MRI findings were divided into three state：slight stage （15 cases, 35.7%）, moderate stage （19 cases, 45.2%）, severe stage （8 cases, 19.5%）. Among them, subarachnoid hemorrhage was in 17 cases, cerebral hemorrhage in 4 cases, intraventricular hemorrhage in 2 cases. Conclusion MRI is a valuable means in the early diagnosis of hypoxia-ischemia encephalopathy.
