| 摘 要： | 探讨动脉自旋标记全脑容积灌注成像（3D-ASL)对短暂性脑缺血发作(TIA)的诊断价值。对48例临床诊断短暂性脑缺血发作的患者据最后一次发作24 h内行磁共振常规扫描（包含T1WI、T2WI、T2-FLAIR、DWI序列)、磁共振血管成像（3D-TOF-MRA)及3D-ASL扫描，并根据扫描结果对48例短暂性脑缺血发作患者进行分析。常规平扫检出异常14例（29.17%）；3D-MRA检出异常18例(37.50%)；3D-ASL检出异常37例(77.09%)。动脉自旋标记全脑容积灌注成像对短暂性脑缺血发作的检出率远高于常规平扫及血管成像,有显著性差异，且简便易行，可以作为诊断短暂性脑缺血发作的常规检查方法予以推广。

| Abstract: | To study the perfusion imaging value of whole brain arterial spin labeling (3D-ASL) in the diagnosis of transient ischemic attack(TIA) 48 cases of patients with transient ischemic attackin 24 hours had MRI routine scan (including T1WI,T2WI,T2-FLAIR,DWI sequence can) magnetic resonance angiography(3D-TOF-MRA) and 3DASL scan,And then were analyzed The routine scan normal were 34 cases (70.83%), abnormal 14 cases (29.17%);3D-TOF-MRA normal 30 cases (62.50%),3D-TOF-MRA abnormal 18 cases (37.50%);3D-ASL normal 11 cases (22.91%), 3D-ASL abnormal 37 cases (77.09%)The detection rate of perfusion imaging of whole brain arterial spin labelingin diagnosis of transient ischemic attack is much higher than that of routine scan and vascular imaging ;and the operation is very simple;and there is a significant statistical difference; which can be used as a diagnostic routine method of transient ischemic attack |
