目的以数字减影血管造影(DSA)的结果为对照标准,评价64层螺旋CT血管成像(CTA)在缺血性脑血管病中的诊断价值。方法选择缺血性脑血管病住院患者53例,分别行CTA、DSA检查,比较两种检查结果的一致性及差异性。结果与对照标准DSA比较,CTA的敏感度为84.9%,特异度为99.1%,准确度为98.7%。结论 CTA检查能清晰显示头颈部血管狭窄性病变,简捷、无创,可作为缺血性脑血管病患者评价的重要方法。
Objective To evaluate the value of 64-slice spiral CT angiography (CTA) in the diagnosis of ischemic cerebrovascular disease by using digital subtraction angiography (DSA) as a control. Methods Fifty-three inpatients with ischemic cerebrovascular disease were selected and examined by CTA and DSA respectively. The consistency and difference of the two test results were compared. Results Compared with the standard DSA, the sensitivity of CTA was 84.9%, the specificity was 99.1% and the accuracy was 98.7%. Conclusion CTA examination can clearly show the stenosis of the head and neck lesions, simple and noninvasive, which can be used as an important method for the evaluation of patients with ischemic cerebrovascular disease.
