Duplex scanning with the use of continuous wave Doppler instrumentation was used for the evaluation of carotid disease and compared to angiography. In twenty such patients 100% accuracy for diagnosis of total occlusion by Duplex scanning with continuous wave Doppler, was obtained. The sensitivity for those patients with 50%-99% stenosis was 92% and for those patients with 20%-49% stenosis was 75%. The overall accuracy for this diagnostic test for all groups of stenosis was 85%. This compares favorably with other noninvasive vascular techniques and is felt to be an accurate and useful technique for the detection of carotid stenosis. Several advantages of this technique are pointed out.
使用连续波多普勒仪器进行双功扫描，用于评估颈动脉疾病，并与血管造影进行比较。在20例此类患者中，连续波多普勒双功扫描诊断完全闭塞的准确率达到了100%。对于狭窄程度在50%-99%的患者，敏感性为92%；对于狭窄程度在20%-49%的患者，敏感性为75%。该诊断测试对所有狭窄组的总体准确率为85%。这与其他非侵入性血管技术相比具有优势，被认为是一种检测颈动脉狭窄的准确且有用的技术。文中指出了该技术的几个优点。
