摘　　要：目的:探讨增强MRA及超声对短暂性脑缺血发作(TIA)病人颈部动脉血管病变的诊断价值。方法:对48例TIA患者分别应用血管彩超、增强MRA检查颈部动脉血管,对检出病变部位、数量进行分析。结果:超声对椎动脉、颈总动脉、颈内动脉的病变检出率分别是27.1%、88.5%、17.7%。3DTRICKS对椎动脉、颈总动脉、颈内动脉的病变检出率分别是77.1%、20.8%、19.8%。应用χ2检验,对椎动脉和颈总动脉病变的检出率,增强MRA和超声之间有显著差异(P均小于0.001);对颈内动脉病变的检出率,增强MRA和超声之间无统计学差异(P>0.05)。结论:对于TIA患者,超声可以作为初筛检查。超声与增强MRA联合检查,可以更全面、准确的评价血管病变,指导临床治疗。Purpose： To investigate the diagnostic value of contrast- enhanced MRA and Ultrasonography in neck vascular lesions in patients with TIA. Methods： The data of 48 patients with TIA examined by color Doppler ultrasonography and contrast- enhanced MRA, including the number and location of pathology were analyzed. Results： The detection rate of ultrasonography in vertebral artery, common carotid artery and internal carotid artery is 27.1%, 88.5% and 17.7% . And the detection rate of contrast- enhanced MRA is 77.1%, 20.8% , and 19.8% respectively. Using Z2 test, there are significant differences in vertebral artery and common carotid artery lesions but no statistical difference in internal carotid artery lesions between contrast - enhanced MRA and Ultrasonography. Conclusion： Ultrasonog- raphy may be a screening examination in TIA patients. Vascular lesions can be evaluated completely and correctly by contrast enhanced MRA combined with Ultrasonography.
