摘　　要：目的:评价磁共振液体衰减反转恢复(FLAIR)技术在结核性脑膜炎中的应用价值。方法:对38例结核性脑膜炎患者均行常规TSE序列T2WI及FLAIR序列检查,由两位有经验的医师分别独立进行分析,对比两种成像序列对结核性脑膜炎脑膜病变的显示能力。结果:38例MRI检查30例出现脑膜异常,共发现102处脑膜受累及,FLAIR序列显示脑膜病变97处,显示率为95.1%,TSE序列T2WI显示脑膜病变82处,显示率为80.4%,两种成像方法显示脑膜病变有显著性差异(P<0.01)。结论:FLAIR技术是一种能明显提高结核性脑膜炎脑膜病变显示率的简便方法,可以作为TBM常规序列而应用。Objective：To assess the application of MRI fluid attenuated inversion recovery （FLAIR） sequence in tuberculous meningitis （TBM）. Methods：Thirty-eight patients with tuberculous meningitis were studied with routine T2-weighted rISE and FLAIR sequences. The two sequences were compared and analyzed by two experienced doctors separately to determine which was better for depicting meningeal lesions. Results： Abnormal meningeal lesions were discovered in 30 patients among the whole 38 patients in MR/examination, 102 lesions were detected with FLAIR sequences, taking 95.1% of the total and 81 with rISE taking 80.4%. Distinction between both of the above mentioned sequences was obvious （ P 〈 0.05）. Conclusion： FLAIR sequence is superior to the conventional TSE sequences in showing the meningeal abnonnalities of TBM, and thus it can be recommended as the conventional sequence for TBM.
