摘　　要：目的探讨64层螺旋CTA与DSA在颈内动脉狭窄的临床应用价值。方法收集临床拟诊为前循环缺血发作的患者203例,进行64层螺旋CTA检查,其中97例患者同时行DSA检查,并将CTA与DSA结果相对照,计算出二者之间的敏感性和特异性。结果本组行CTA检查的203例患者中有181例患者颈内动脉有不同程度的狭窄,97例行DSA检查的患者颈内的动脉均有不同程度的狭窄,CTA与DSA的敏感性和特异性为100%。结论64层螺旋CTA能够清晰地显示颈内动脉系统的异常,在某些方面上可替代DSA检查。Objective To explore the clinical application of 64 - slice spiral CT angiography （ CTA ） and DSA in internal carotid artery stenosis. Methods 203 patients were clinically diagnosed as anterior circulation ischemia, they were examined by 64SCTA, 97 patients of them were examined by DSA. The results of CTA were compared with the that of DSA,the sensitivity and specificity of CTA and DSA were figured out. Results 181 patients of 203 patients examined by CTA were internal carotid artery stenosis. 97 patients examined by DSA were internal carotid artery stenosis. The diagnostic sensitivity and specificity of CTA and DSA were all 100%. Conclusion 64SCTA can demonstrate the changes of internal carotid artery, it can replace DSA in certain fields .
