3D-ASL技术在短暂性脑缺血发作中的应用及其临床意义分析

目的 探讨三维动脉自旋标记技术(3D-ASL)在短暂性脑缺血发作中的应用情况.方法 选择2017年6月到2018年12月之间在我医院神经内科接受治疗的患者25例作为观察组,选择同期健康志愿者25例作为对照组,对两组进行常规的MRA检查和3D-ASL检查,比较各项检查在短暂性脑缺血发作诊断和评估方面的情况.结果 50例患...

Application of 3D-ASL Technique in Transient Ischemic Attack and Its Clinical Significance

Objective To investigate the application of three dimensioned a rterial spin labeling(3 D-AS L) in tra nsient ischemic attack.Methods Twenty-five patients who underwent neurology in our hospital from June2017 to December 2018 were selected as observation group.25 healthy volunteers were selected as the control group.MRA and 3 D-ASL were performed to compare the status of each examination in the diagnosis and evaluation of transient ischemic attacks.Results All the 50 patients were negative by DWI.The differences were not statistically significant(P>0.05).The positive rate of TIA in the observation group was 52%,and the positive rate of TIA in the 3 D-ASL group was 80%,which was statistically significant(P<0.05).There was no significant difference in the control group(P>0.05).Compared with MRA,3 D-ASL technical examination showed statistically significant diffe rences in accuracy,sensitivity,specificity,positive predictive value and negative predictive value(both P<0.05).Conclusion The application of 3 D-ASL technology in transient ischemic attack is superior to MRA routine examination method in sensitivity and specificity,and has good performance in diagnosis and evaluation.It is worthy of promotion in the clinical scope.
