目的 探究MRI诊断小儿病毒性 脑炎及应用价值，为临床治疗小儿病 毒性脑炎提供指导。方法 抽取来我院 就医的50例小儿病毒性脑炎患儿(2014 年5月至2016年5月)作为此次实验的目 标对象，对50例小儿病毒性脑炎患儿均 实施CT诊断、MRI诊断，研究对比CT诊 断和MRI诊断的检出结果。结果 MRI诊 断的检出率(94.00%)显著高于CT诊断 (72.00%)，P＜0.05。结论 对小儿病毒 性脑炎患儿采取MRI诊断具有较高的检出 率，临床意义显著。

Objective To investigate the application value of MRI in diagnosing children virus encephalitis and provide guidance for children virus encephalitis. Methods 50 cases with children virus encephalitis in our hospital from May 2014 to May 2016 were selected as study objects and given CT diagnosis, MRI diagnosis. Compare the detection results of the two methods. Results Detection rate of MRI diagnosis (94.00%) was significantly higher than CT diagnosis (72.00%),P＜0.05. Conclusion MRI in diagnosing children virus encephalitis has higher detection rate and significant clinic effect.
