扩散加权成像技术在HIE患儿预后评估中的价值

目的探讨扩散加权成像技术在新生儿缺氧缺血性脑病（HIE）预后评估中的价值。方法回顾性分析96例临床确诊为HIE患儿的所得资料。将96例患儿分为A组和B组,A组采用常规核磁检查,B组采用扩散加权成像技术检查。观察两种检查方法在HIE诊断中的影像学特点,并随访患儿的预后。结果两组患儿一般情况比较差异无统计学意义（P〉0.05）。A组检出影像学变化21例,随访预后不良7例,B组检出影像学变化32例,随访预后不良19例;B组HIE患儿的预后评估价值明显高于A组（P〈0.05）。结论扩散加权成像可充分反映HIE患儿的病理变化和脑损害,对评估HIE患儿的预后具有一定的应用价值,有利于临床及早采取干预治疗措施。

The value of diffusion-weighted imaging in prognosis evaluation to HIE children

Objective To study the value of diffusion-weighted imaging in prognosis evaluation to HIE children.Method Total of 96 children were diagnosed hypoxic-ischemic encephalopathy（HIE）,and randomly divided into 2 groups,group A apply conventional magnetic resonance imaging examination and group B apply diffusion-weighted imaging technology.Compare the imaging characteristics of the two examination technology in HIE diagnosis.Follow up was preformed for the prognosis of HIE children.Result The general state between the two groups showed statistical significant difference（P0.05）.Group A detected 21 cases with imaging change,7 cases were followed up for a poor prognosis;prognostic value of HIE infants in group B significantly higher than that of group A （P0.05）.Conclusion Diffusion-weighted imaging may reflect the pathological changes and brain damage in HIE,and is valuable in assessing the prognosis of children with HIE,and can benefit to have early intervention treatment.
