The results of continuous wave Doppler scanning of 96 common carotid arteries and their immediate branches were compared with those of selective angiography. The overall accuracy of the Doppler technique for the assessment of the common, internal and external carotid arteries was 98%, 81% and 86%, respectively with a sensitivity of 60%, 70% and 54%, and a specificity of 100%, 93%, and 96%. When stenoses of 50% were considered hemodynamically insignificant, the overall accuracy of the assessment of the common, internal and external carotid arteries rose to 100%, 93% and 93%, but the sensitivity was only 100%, 83% and 53%, whereas the specificity was 100%, 96% and 96%. This modality did not prove useful in the detection of intimal ulcers and plaques nor could the degree of stenosis be accurately graded. The above data indicate that contrast angiography remains imperative prior to surgery.
对96条颈总动脉及其直接分支进行连续波多普勒扫描的结果与选择性血管造影的结果进行了比较。多普勒技术评估颈总动脉、颈内动脉和颈外动脉的总体准确率分别为98%、81%和86%，敏感性分别为60%、70%和54%，特异性分别为100%、93%和96%。当认为50%的狭窄在血流动力学上无意义时，评估颈总动脉、颈内动脉和颈外动脉的总体准确率升至100%、93%和93%，但敏感性仅为100%、83%和53%，而特异性为100%、96%和96%。这种方法在检测内膜溃疡和斑块方面未被证明有用，也无法准确分级狭窄程度。上述数据表明，术前仍必须进行造影血管造影。
