【摘要】：目的:探讨3D-ASL联合MRA在DWI阴性TIA患者中的临床应用价值。方法:回顾性分析临床确诊的DWI阴性TIA患者的3D-ASL及MRA资料共55例,正常对照组的3D-ASL及MRA资料共32例,分析病变的检出率、血管狭窄程度与r CBF比值的关系及两组的差别。结果:3D-ASL诊断TIA的敏感性为70.91%;在血管的轻度狭窄、分支稀少及中度狭窄中病例组与对照组有统计学差异(P0.05),在重度狭窄组两者无统计学差异(P0.05)。结论:3D-ASL与MRA联合应用既能显示脑组织灌注异常范围及程度,又能明确血管病变部位及狭窄程度,提高DWI阴性TIA诊断的特异性及敏感性,为临床精细、个体化的治疗方案提供重要依据。
[Abstract]:Objective: to evaluate the clinical value of 3D-ASL combined with MRA in DWI negative TIA patients. Methods: the data of 3D-ASL and MRA in 55 patients with DWI negative TIA and 32 patients with 3D-ASL and MRA in normal control group were analyzed retrospectively. The detection rate of pathological changes, the relationship between the degree of stenosis and the ratio of r CBF and the difference between the two groups were analyzed. Results the diagnostic sensitivity of TIA was 70.91.The sensitivity of the two groups in the diagnosis of TIA was significantly higher than that in the control group (P 0.05), but no significant difference was found in the severe stenosis group (P 0.05). Conclusion the combination of MRA and W3D-ASL can not only show the extent and extent of cerebral perfusion abnormalities, but also identify the location and stenosis of vascular lesions, and improve the specificity and sensitivity of DWI negative TIA diagnosis. Individualized treatment program provides important basis.
