摘　　要：目的对比T2Flair增强序列及三维快速扰相梯度回波(3D FSPGR)T1WI增强序列对儿童脑膜炎的诊断价值。方法收集我院自2012年6月至2014年9月间经临床证实患有脑膜炎的儿童22例,常规磁共振成像(MRI)扫描后行增强T2Flair序列及3D FSPGR T1WI序列扫描。结果 22例病例中,增强T2Flair序列发现所有病例均有不同程度的脑膜强化,未显示0例;3D FSPGR T1WI序列对脑膜强化显示15例,未显示7例。2种序列对显示病变差异具有统计学意义(P<0.05)。结论 T2Flair增强序列可清晰显示儿童感染性脑膜炎脑膜强化,应作为儿童脑膜炎MRI检查的首选扫描序列。3D FSPGR T1WI增强序列可作为T2Flair增强序列的补充。Objective To evaluate the diagnostic value of contrast-enhanced T2 Flair sequence and contrast-enhanced 3D fast spoiled gradient recalled echo （3D FSPGR） T1WI sequence in detection of meningitis in children. Methods Twenty-two children （Jun, 2012-Sep, 2014） with meningitis collected from our hospital underwent magnetic resonance imaging （MRI） plain scan, enhanced T2 Flair sequence scan and enhanced 3D FSPGR T1WI sequence scan. Results The enhanced T2 Flair sequences found that all children had different degrees of meningeal enhancement in the 22 cases. In which clearly showed 22 cases, and have not showed 0 case. The enhanced 3D FSPGR T1WI sequence clearly showed 15 cases, and have not showed 7 cases. The difference between the number of meningeal enhancement was statistically significant （P〈0.05）. Conclusion Enhanced T2 Flair sequence can elearly show the meningeal enhancement of meningitis in children, and it can detect more lesions than the enhanced 3D FSPGR T1WI sequence. The contrast-enhanced 3D FSPGR T1WI sequence can be used as the supplement of contrast-enhanced T2 Flair sequence.
