摘要
目的：着重研究FLAIR成像对多发性硬化的诊断与鉴别诊断价值，为临床治疗提供更多的影像学信息。材料和方法：经临床和MRI确诊的MS患者28例，男性13例，女性15例，年龄范围10-59岁，平均34．5岁。所有病例均行SET1WI、TSE T2WI和FLAIR序列成像。通过计数评价该3个序列成像对MS病灶的显示能力，对结果行两因素方差分析。结果：SET1WI、TSET2WI、FLAIR对脑室周围、皮层下及总体病灶个数的显示均有显著性差异。TSE、FLAIR对脑室周围、皮层下的病灶显示个数无显著性差异。在显示病灶总体个数上TSET2WI与FLAIR有显著性差异。结论：MS的常规MRI扫描应有SE T1WI、TSE T2WI、FLAIR序列。FLAIR对病变的检出比TSE T2WI、SE T1WI更敏感。
Objective： The purpose of this study is to investigate the value of spin echo （SE）, turbo spin echo （TSE） and fluid attenuated inversion recovery （FLAIR） for Multiple Sclerosis （MS）, so as to provide more valuable imformation for clinical therapy. Method： SE, TSE, FLAIR images were obtained in 28 MS patients （ 13 males, and 15 females, age ranged 10 - 59years, average age 34.5years）. All of the data were processed： 1. The recognition ability of SE T1WI, TSE T2WI, FLAIR image for MS were evaluated by calculating the number of lesions. All of the results were analysed by two - way anova using SPSS 11.5 software. Resullt： The number of the lesion in paraventricular and subcortical regions and the total number displayed in TSE and FLAIR were higer than that in SE. There was no significant difference between TSE and FLAIR in the number of lesion in the paraventricular and subcortical region, but the total number of the lesions had significant difference between TSE and FLAIR. Conclusion： The routine examination of MS should include SE T1WI, TSE T2WI and FLAIR sequences. FLAIR was more sensitive than TSE T2WI and SE T1WI.
