目的 探析MRI不同扫描序列组 合在诊断新生儿缺血缺氧脑病临床诊 断中的应用及其价值。方法 选择我院 2012年6月-2015年6月收治的64例缺血 缺氧脑病新生儿作为研究对象，观察不 同扫描序列影像学表现并比较不同扫描 序列组合的诊断准确率。结果 cMRI、 cMRI+DWI、cMRI+SWI、cMRI+DWI+SWI的 确诊率分别为43.8%、64.1%、67.2%、 82.8%，cMRI+DWI+SWI序列诊断准确率 最高，与cMRI其它三种扫描序列确诊率 相比均有统计学意义(P＜0.05）。结论 cMRI+DWI+SWI扫描序列在新生儿缺血缺 氧脑病临床诊断中的应用可全面反映新 生儿HIE病灶范围、类型及病理演变过 程，诊断准确临床更高，为治疗方案的 优化及预后评估提供丰富影像学依据。

Objective To explore the application and value of MRI different scanning sequences in the diagnosis of neonatal hypoxic ischemic encephalopathy. Methods 64 cases of neonatal hypoxic ischemic encephalopathy who were admitted into the hospital during June 2012 to June 2015 were selected as the research objects. The imaging findings of different scanning sequences were observed and the diagnostic accurate rates of different scanning sequences were compared. Results The diagnostic rates of cMRI, cMRI+DWI, cMRI+SWI and cMRI+DWI+SWI were 43.8%, 64.1%, 67.2% and 82.8%, respectively. The diagnostic accuracy of cMRI+DWI+SWI was the highest. Compared with the diagnostic accurate rates of cMRI other three kinds of scanning sequences, there was statistical significance (P<0.05). Conclusion The application of cMRI+DWI+SWI scanning sequence in the diagnosis of neonatal hypoxic-ischemic encephalopathy can comprehensively reflect the scope, type and pathological changes of neonatal HIE and the diagnostic accurate rate is relatively higher, which provide a rich imaging basis for the optimization of treatment plan and prognosis evaluation.
