摘要
目的:比较磁共振血管成像(MRA)检查与磁共振三维动脉自旋标记(3D-ASL)检查在短暂性脑缺血发作(TIA)诊断中的效能。方法:选取93例疑似TIA的患者为研究对象,均行MRA与3D-ASL检查,以动态磁敏感对比增强灌注成像(DSC-PWI)检查结果为金标准,比较MRA检查与3D-ASL检查在TIA诊断中的效能。结果:DSC-PWI检查结果显示,93例疑似TIA患者中,61例为阳性,32例为阴性;3D-ASL检查诊断TIA的灵敏度、准确度均高于MRA检查诊断,差异有统计学意义(P<0.05);3D-AS检查诊断TIA的特异度与MRA检查诊断比较,差异无统计学意义(P>0.05)。结论:3D-ASL检查诊断TIA的灵敏度、准确度均高于MRA检查诊断。
Objective:To investigate efficacies of magnetic resonance angiography(MRA)and magnetic resonance three-dimensional arterial spin labeling(3D-ASL)in diagnosis of transient ischemic attack(TIA).Methods:93 patients with suspected TIA were selected as the research objects,and all of them underwent MRA examination and 3D-ASL examination.Using the results of dynamic susceptibility contrast perfusion weighted imaging(DSC-PWI)as the gold standard,the efficacies of MRA and 3D-ASL in the diagnosis of TIA were compared.Results:DSC-PWI examination showed that 93 cases had suspected TIA,61 cases were positive and 32 cases were negative.The sensitivity and accuracy of 3D-ASL diagnosis of TIA were higher than those of MRA diagnosis,and the differences were statistically significant(P<0.05).However,there was no statistically significant difference in the specificity between 3D-ASL and MRA(P>0.05).Conclusions:The sensitivity and accuracy of 3D-ASL diagnosis of TIA are higher than those of MRA diagnosis.
