摘　　要：目的:评价超声造影对颅外段颈动脉狭窄的诊断价值。方法:对16例颅外段颈动脉狭窄患者进行超声造影和DSA检查,分别在所获得的图像上测量颈动脉狭窄的直径狭窄率,并对两组数据进行统计分析。结果:本组超声造影共发现颈动脉血管狭窄39处,37处与DSA分级相符合,假阳性2处,其中颈动脉颅外段狭窄的敏感性、特异性、准确度分别为100%,97.8%～99.0%、97.9%～98.5%(K值=0.928～1)。结论:超声造影是对颅外段颈动脉狭窄筛查、术前评估、术后随访的最佳检查方法,能基本替代DSA检查。Objective：To assess the diagnostic value of contrast-enhanced ultrasound in carotid stenosis. Methods： Sixthteen patients with earodid stenosis underwent eontrast-erdranced ultrasound and digital substraction angiography （DSA） contemporaneously, the diame- ter of stenosis in carotid was measured and the result between two methods was evaluated. Results： In this group, 39 carotid stenosises were found by eontrast-enhaneed ultrasound image, of which 37 stenosises were diagnosed with beth examinations, two stenosises were highly suspected as no carotid stenosis under-went Contrast-enhanced ultrasound. The sensitivity of Contrast-enhanced ultrasound was 100%, the specificity was 97.8%～99%, and the acaueacy was 97.9% ～ 98.5% （K= 0.928 ～ 1） in contrast-enhanced ultrasound eraniocervieal artery. Conclusion： Contrast-enhanced ultrasound has dsmonstrated the stenosis of craniocervical arteries with reliability and can take place of DSA.
