摘　　要：目的:初步探讨并行采集平面回波联合液体衰减反转恢复系列技术(ASSET-EPI-FLAIR,AE-FLAIR)在危急脑梗死病变中的诊断价值.方法:90例危急脑梗死患者全部行轴位SE-T1、FSE-T2、FLAIR及AE-FLAIR扫描,分别比较FLAIR和AE-FLAIR对脑梗死灶显示清晰度及检查成功率.所得数据均用SPSS13.0配对资料卡方检验进行处理,P<0.05有统计学意义.结果:(1)90例共检出120个梗死灶,在FLAIR、AE-FLAIR显示清晰率分别为64%、85%(x2=13.738,P=0.000 1);其中50例检查时配合者共检出梗死灶70个,在FLAIR、AE-FLAIR显示清晰率分别为90%、94%(x2=0.888,P=0.266);40例检查时不配合者共检出梗死灶50个,在FLAIR、AE-FLAIR显示清晰率分别为28%、72%(x2=19.360,P=0.000 1).(2)90例在FLAIR、AE-FLAIR检查成功率分别为47%,100%(x2=61.791,P=0.000 1).结论:AE-FLAIR不但成像时间短及图像质量较好,而且它有FLAIR加权又有DWI加权图像效果,有利于脑梗死早期诊断,特别是对于伴有神志不清及呼吸衰竭等症状检查不配合患者,因此认为可用AE-FLAIR取代FLAIR技术.Aim:To explore the value of ASSET-EPI-FLAIR (AE-FLAIR)technique in diagnosis of critical cerebral infarction.Methods:Ninety cases of critical cerebral infarction underwent axial SE-T1, FSE-T2,FLAIR and AE-FLAIR scanning.In 90 cases were inspected 120 cerebral infarctions,com-pared with FLAIR and AE-FLAIR on cerebral infarct display definition and the success rate of inspection. The obtained data were used SPSS 13.0 paired chi square test for processing,P <0.05 had statistical significance.Results:Ninety cases were detected in 120 infarct clear rate in FLAIR,AE-FLAIR display are respectively 64%,85% (2 =13.738,P =0.000 1).Fifty cases of being cooperative with exami-nation were detected 70 infarctions respectively in FLAIR,AE-FLAIR clear display rate 90%,94% (2=0.888,P =0.266).Forty cases of conld not cooperated with examination were detected 50 infarctions respectively in FLAIR,AE-FLAIR clear display rate 28%,72% (2 =19.360,P =0.000 1).The 90 patients in the FLAIR and AE-FLAIR of the successful rate was respectively 47%100% (2 =61.791, P =0.000 1).Conclusion:AE-FLAIR not only has short imaging time and image quality,but also has the FLAIR weighted and DWI weighted images,it is conducive to early diagnosis of cerebral infarction, especially in patients of being uncooperative with unconsciousness and respiratory failure symptoms check,we think that AE-FLAIR can instead of FLAIR technology.
