弥散加权成像对新生儿缺氧缺血性脑病的早期诊断价值

摘要

目的：评价磁共振弥散加权成像（DWI）对新生儿缺氧缺血性脑病（HIE）的早期诊断价值。方法选取2012年6月-2015年6月在湖南省南华大学附属第二医院新生儿科住院诊断为HIE的32例新生儿进行研究，在生后72 h内进行常规T1WI、T2WI和DWI检查。结果在生后72 h内，32例HIE患儿中，仅2例常规T1WI、T2WI表现异常，但DWI可见异常高信号。结论在新生儿HIE的早期诊断中，DWI较常规T1WI、T2WI更有诊断价值。%Objective To evaluate the diagnostic value of magnetic resonance diffusion weighted imaging (DWI) in neonatal hypoxic ischemic encephalopathy (HIE). Methods Thirty-two neonatal cases diagnosed as hypoxic ischemic encephalopathy in the Neonatal Department of the Second Affiliated Hospital of Nanhua Uni_versity from June 2012 to June 2015 were studied. Routine T1WI, T2WI and DWI examinations were carried out within 72 hours after birth. Results In 72 hours after birth, abnormal high signals were visible in DWI, but only 2 of 32 cases with HIE had abnormal performance in the conventional T1WI and T2WI examina_tions. Conclusions In the early diagnosis of neonatal hypoxic ischemic encephalopathy, DWI has higher diag_nostic value than conventional T1WI and T2WI.
