Phonoangiography, as a noninvasive quantitative analysis of arterial bruits, was conducted just prior to standard invasive radiographic angiography in 135 patients. Sound records from 162 carotid arteries were analyzed with a new processing technique employing a high speed analog acoustic analyzer, the autocorrelator. In 18 arteries with carotid stenosis, a correlation coefficient of 0.87 resulted between phonoangiographic diameter predictions and radiographic diameter estimates. Bruit analysis identified two patients with patent lumen diameters, but tortuous carotid vessels. One hundred thirty-three carotid arteries had no bruits that could be analyzed, but angiograms showed no extracranial stenosis. Four arteries from which bruits could not be analyzed were found to be totally occluded. Carotid phonoangiography appears applicable in approximately one of seven patients now requiring angiography of head and neck vessels. When applicable, phonoangiography is significantly correlated with angiographic findings.
作为一种对动脉杂音的无创定量分析方法，在135例患者中，在进行标准的有创放射造影血管造影之前进行了血管音图检查。使用高速模拟声学分析仪（自相关器）的一种新处理技术对来自162条颈动脉的声音记录进行了分析。在18条有颈动脉狭窄的动脉中，血管音图直径预测与放射造影直径估计之间的相关系数为0.87。杂音分析发现两名患者管腔直径正常，但颈动脉迂曲。133条颈动脉没有可分析的杂音，但血管造影显示无颅外狭窄。发现4条无法分析杂音的动脉完全闭塞。颈动脉血管音图检查似乎适用于目前约七分之一需要进行头颈部血管造影的患者。当适用时，血管音图检查与血管造影结果显著相关。
