Forty-six consecutive studies of carotid bifurcations were done with a Hokanson Ultrasonic Arteriograph before contrast arteriography. Based on the Doppler signal and the oscilloscopic image, each internal carotid artery was sorted into one of four categories as an estimation of the percent diameter reduction: less than or equal to 10 percent, 10 percent to 49 percent, 50 percent to 99 percent, and total occlusion. These results were compared with the percent diameter reduction determined from contrast arteriograms by a vascular radiologist unaware of the noninvasive test results. Overall, 83 percent of the arteries were correctly categorized. Detection of stenosis in the 50 percent to 99 percent range was 89 percent accurate. The sensitivity and specificity in detecting a 50 percent or greater stenosis were both 96 percent.
在进行造影动脉造影之前，使用霍坎森超声动脉造影仪对46例连续的颈动脉分叉进行了研究。根据多普勒信号和示波器图像，将每条颈内动脉分为四类之一，以估计直径缩小百分比：小于或等于10%、10%至49%、50%至99%以及完全闭塞。将这些结果与一位不知道无创检测结果的血管放射科医生从造影动脉造影片确定的直径缩小百分比进行比较。总体而言，83%的动脉被正确分类。在50%至99%范围内狭窄的检测准确率为89%。检测50%或更高狭窄的敏感性和特异性均为96%。
