目的：探讨在颅颈动脉狭窄和斑块的诊断中64层螺旋CT血管造影(CTA)的应用价值。方法95例符合标准的缺血性脑血管病患者作为实验组,以同期52例诊断为非缺血性脑血管病患者作为对照组,2周内行64层螺旋CTA扫描。结果实验组95例患者中存在斑块者81例,斑块检出率为85.3%,高于对照组36.5%,缺血性脑血管病患者的颅颈动脉狭窄和斑块的检出率,混合斑块和软斑块的总比例均高于对照组,差异均有统计学意义(P<0.05)。结论64层螺旋CTA在诊断缺血性脑血管病患者动脉狭窄和斑块方面具有较高的应用价值。%Objective To explore the application value of 64-slice spiral CT angiography (CTA) in diagnosis of cranial carotid stenosis and plaque. Methods There were 95 patients with standard ischemic cerebrovascular disease as experimental group, and another 52 patients without standard ischemic cerebrovascular disease in the same time period as control group. 64-slice spiral CTA was applied for them within 2 weeks. Results Among the 95 cases in the experimental group, there were 81 cases with plaques. The plaque detection rate was 85.3%, which was higher than 36.5%of the control group. The detection rates of cranial carotid stenosis and plaque, and the total proportion of mixed plaques and soft plaques in patients with ischemic cerebrovascular disease were higher than those in the control group, and the difference had statistical significance (P<0.05). Conclusion 64-slice spiral CTA has high application value in diagnosis for cranial carotid stenosis and plaque in ischemic cerebrovascular disease patients.
