重症小儿手足口病合并脑炎78例的MRI影像分析

[目的]探讨MRI影像检查对小儿手足口病合并脑炎的诊断价值.[方法]回顾性分析78例小儿手足口病合并脑炎患者的MRI影像资料,统计MRI检出率,分析其影像学特征.[结果]MRI检出率为71.8%（56/78）,其中病灶T1WI为低信号者44.87%（35/78）,T2WI为高信号56.41%（44/78）,FLAIR/T2WI高信号60.26%（47/78）,DWI为高信号65.38%（51/78）.[结论]MRI可作为小儿手足口病并发脑炎的首选影像诊断手段,其中FLAIR/T2WI和DWI对小儿手足口病并发脑炎十分敏感,且能做出明确诊断

MRI Analysis of 78 Cases of Severe Pediatric Hand-foot-mouth Disease with Encephalitis

[Objective] To explore the value of magnetic resonance imaging（MRI） in the diagnosis of pediatrichand-foot-mouth disease（HFMD） with encephalitis. [Methods] MRI data of 78 cases of HFMD with encephalitis were analyzed retrospectively. The detection rate of MRI was accounted. The imagine features were analyzed. [Results] The detection rate of MRI was 71.8%（15/78）. There were 35 cases（44.8%） with low signal T1WI, 44 cases（56.41%） with high signal T2WI, 47 cases（60. 26%） with high signal FLAIR/T2WI and 51 cases（65.38%） with high signal DWI. [Conclusion] MRI can serve as the first choice of the imaging diagnostic method for pediatric HFMD with encephalitis. FLAIR/T2WI and DWI are very sensitive to pediatric HFMD with encephalitis and can be used as the definite diagnosis of this disease.
