Oculoplethysmography-carotid phonoangiography and periorbital directional Doppler sonography are two techniques widely used in the noninvasive evaluation of possible carotid artery disease. Recent advances with sonographic Doppler devices now permit measurement of blood velocities in the extracranial carotid arteries by direct scanning with a color coded Doppler imaging system. A prospective study involving 216 patients being evaluated for possible carotid insufficiency was carried out to compare the results obtained with these three methods. With stenosis 65% or greater at angiography, the accuracy of the Doppler imaging system was 94%, that of oculoplethysmography-carotid phonoangiography was 84%, and that of periorbital directional Doppler sonography was 80%. These results demonstrate that direct Doppler examination of the carotid bifurcation is superior to either of the other two techniques for the detection of carotid artery stenosis.
眼体积描记法-颈动脉血管音造影术和眶周定向多普勒超声检查是广泛用于无创评估可能的颈动脉疾病的两种技术。超声多普勒设备的最新进展现在允许通过彩色编码多普勒成像系统直接扫描来测量颅外颈动脉的血流速度。进行了一项涉及216例可能存在颈动脉供血不足的患者的前瞻性研究，以比较这三种方法获得的结果。血管造影显示狭窄65%或更高时，多普勒成像系统的准确性为94%，眼体积描记法-颈动脉血管音造影术为84%，眶周定向多普勒超声检查为80%。这些结果表明，对颈动脉分叉进行直接多普勒检查在检测颈动脉狭窄方面优于其他两种技术中的任何一种。
