目的：介绍快速FLAIR技术在椎管内病变MRI中的应用并评价其价值。方法：用0．5T超导型MR扫描仪在常规T1、T2WI后对44例椎管内病变患者进行快速FLAIR成像，TR：5 000～6 000 ms，TI：1 500～2 000 ms，TE：90～120 ms。35例在快速FLAIR成像后再行T1WI增强扫描。结果：椎管内髓外肿瘤26例，髓内肿瘤4例，脊髓炎症11例，脊髓局限性坏死软化3例。快速FLAIR图像清楚地显示所有病变，而常规T2加权像对9例髓外硬膜下肿瘤及8例脊髓炎显示不佳。结论：快速FLAIR技术在椎管内病变MRI中具有较高的应用价值，是常规T2加权像的必要补充。

Objective:To evaluate the usefulness of fast FLAIR pulse sequence in the MRI of intraspinal canal disease.Methods:Forty-four patients with suspected intraspinal canal disease were imaged with fast FLAIR pulse sequence after routine T1 and T2 weighted imaging in a 0.5 T superconducting MR scaner.The parameters of FLAIR were TR/TI/TE=6000/1500～2000/90～120 ms.Results:There were 26 intraspinal extramedullary tumors,4 intramedullary tumors,11 myelitis,3 localized ischemic necrosis or malacia of spinal cord.The images of FLAIR pulse sequence clearly detected all lesions of the 44 cases.They were superior to routine T2 weighted images in demonstrating the extent of the lesions and their T2 signal character,expecially in inflammatory disease of spinal cord.Conclusion:FLARI is a very useful pulse sequence in the MRI of intraspinal canal disease,it may be use as an important supplement of routine T2 weighted sequence.
