目的探讨快速液体衰减反转恢复(FLAIR)技术在急性脊髓炎中的应用价值. 方法用0.5T超导磁共振(MR)机对52例健康者和33例急性脊髓炎患者行MR检查,扫描序列为TlM.T2WI,FLAIR序列,33例患者中23例作了T1WI增强扫描,比较FLAIR和TSE-T2WI两种序列对病灶的显示能力. 结果 33例患者33处病灶,FLAIR发现病灶33处,检出率100%,TSE-T2WI发现病灶23处.检出率69.7%:在显示病灶边缘情况方面,FLAIR显示清楚者32例,T2WI显示清楚者13例.在发现病灶及显示病灶边缘方面两者差异有统计学意义(P<0.01). 结论 FLAIR技术在脊髓炎的诊断中有较高的临床应用价值.应作为本病检查的常规方法.

Objective To study the clinical diagnostic value of fluid-attenuated inversion recovery(HAIR)pulse sequence in low-field MR for the acute myelitis.Methods Fifty-two healthy controls and 33 patients with acute myelitis were imaged with TIWI,T2WI and FLAIR imaging in a 0.5T superconducting MR SCalHler,and among them,23 patients were imaged with TlMI after the injection of Gd-DTPA.The detectable abilities of lesions with FLAIR and TSE-T2W1 were compared.Results The FLAIR imaging showed 33 lesions(100%),but the TSE-T2WI only showed 23 lesions (69.7%)inthe 33 cases;32 lesions were clear with FLAIR in demonstrating the border of lesions,and 13 lesions with TSE-T2WI Therefore,the FLAIR sequence were superior to TSE-T2WI in demonstrating the border of lesions and displaying the lesions(P<0.01).Conclusion FLAIR is a very useful sequence in the low-field MR for the acute myelitis.and it should be used as a routine diagnostic method for the acute myelitis.
