摘要
目的:分析MR三维动脉自旋标记(three-dimensional arterial spin labeling,3D-ASL)技术联合磁共振血管成像(magnetic resonance angiography,MRA)诊断短暂性脑缺血发作(transient ischemic attack,TIA)的临床价值。方法:收集2015年8月至2018年8月在河南省中医院住院且临床诊断为TIA的患者92例,均行MR弥散加权成像(diffusion weighted imaging,DWI)、MRA及3D-ASL检查,对病变检出率进行统计分析。结果:92例TIA患者,MR-DWI均显示阴性。MRA联合3D-ASL检查诊断的敏感度为78.26%(72/92),明显高于单一MRA(51.09%)或3D-ASL检查(63.04%),差异有统计学意义(P<0.05)。其中MRA与3D-ASL均显示阳性37例,MRA显示阳性而3D-ASL显示阴性14例,MRA显示阴性而3D-ASL显示阳性21例,二者均显示阴性20例。结论:3D-ASL联合MRA检查能够提高TIA的诊断率。
Objective: To analyze the clinical value of MR three-dimensional arterial spin labeling (3D-ASL) combined with magnetic resonance angiography (MRA) in the diagnosis of transient ischemic attack (TIA). Methods: Ninetytwo patients clinically diagnosed with TIA in the hospital from August 2015 to August 2018 were enrolled. All patients underwent MR routine scan (DWI, etc.), MRA and 3D-ASL. Detection rates of lesions were statistically analyzed. Results: MR-DWI was negative in 92 patients with TIA. The sensitivity of diagnosis by MRA combined with 3D-ASL was 78.26%(72/92), which was significantly higher than that by MRA (51.09%) or 3D-ASL (63.04%) alone (P<0.05). There were 37 cases showing masculine by both MRA and 3D-ASL, 14 cases showing masculine by MRA and feminine by 3D-ASL, 21 cases showing feminine by MRA and masculine by 3D-ASL,and 20 cases showing feminine by both of the two. Conclusion: 3D-ASL combined with MRA can improve the diagnostic rate of TIA.
