摘　　要：目的探讨低磁场MRI对新生儿缺氧缺血性脑病（HIE）的诊断价值。方法对53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：53例新生儿中有45例脑水肿，T1WI侧脑室周围深部脑白质高信号44例，蛛网膜下腔出血及硬膜下出血34例，脑实质出血3’例，灰白质分界不清31例。结论低磁场MRI对HIE有重要的诊断价值。Objective To investigate the value of MRI in the diagnosis of hypoxia--ischemia encephalopathy （ HIE ） .Methods MRI was performed in 53 neonates with hypoxia--ischemiaencephalopathy.All findings were analyzed.Results All patients had diferent brain damage.Of 53 cases during theirneonatal period, brain edema was seen in 45, bilateral basal ganglia hyperintensity on T1WI in 44, SAH orSDH in 34, loss of gray white matter differentiation in 3, cerebral hemorrhage in 31 .Conclusions MRI is helpful for diagnosis HIE.
