The accuracy of oculoplethysmography (OPG) and carotid phonoangiography (CPA) singly and in combination, the Doppler velocity detector, and photoplethysmography (PPG) was checked by measurement of the degree of stenosis as shown on arteriograms in 308 internal carotid arteries. In a second study using arteriographic measurement in 210 internal carotid arteries, the comparative accuracy of the fluid-filled (Kartchner) and the air-filled (Zira) OPG, each with and without CPA, was assessed. In the first study the specificity in arteries with less than 40% diameter reduction varied from 88% for the PPG to 97% for the Doppler examination. The sensitivity in arteries with more than 40% diameter reduction varied from 17% for the Doppler examination to 80% for the combination of OPG plus CPA. For arteries with a reduction in diameter greater than 70%, the sensitivity varied from 67% for the CPA to 87% for the OPG plus CPA. The sensitivity of the OPG plus CPA for total occlusions was 93%. For bilateral carotid artery stenosis over 40%, the sensitivity varied from 50% for the CPA to 82% for the combined OPG plus CPA. In the second study, for arteries with less than 40% stenosis the specificity varied from 86% for the Zira computed readout to 93% for the OPG(K). In the second study, when retrospectively analyzed, the sensitivity for arteries with more than 40% stenosis varied from 74% for the Zira computed readout to 88% for the combined OPG(K) plus CPA. For arteries with greater than 70% diameter reduction the sensitivity varied from 79% for the Zira readout to 100% for OPG plus CPA. For bilateral carotid artery disease with greater than 40% diameter reduction, the sensitivity ranged from 50% for OPG(Z) to 77% for OPG(Z) plus CPA.
通过测量308条颈内动脉血管造影所示的狭窄程度，对眼体积描记法（OPG）、颈动脉血管音造影法（CPA）单独及联合应用、多普勒速度检测仪和光体积描记法（PPG）的准确性进行了检查。在第二项研究中，对210条颈内动脉进行血管造影测量，评估了充液式（卡特chner）和充气式（齐拉）OPG分别在有和没有CPA情况下的相对准确性。在第一项研究中，直径缩小小于40%的动脉的特异性从PPG的88%到多普勒检查的97%不等。直径缩小大于40%的动脉的敏感性从多普勒检查的17%到OPG加CPA联合检查的80%不等。对于直径缩小大于70%的动脉，敏感性从CPA的67%到OPG加CPA联合检查的87%不等。OPG加CPA对完全闭塞的敏感性为93%。对于双侧颈动脉狭窄超过40%的情况，敏感性从CPA的50%到OPG加CPA联合检查的82%不等。在第二项研究中，对于狭窄小于40%的动脉，特异性从齐拉计算读数的86%到OPG（K）的93%不等。在第二项研究中，回顾性分析时，狭窄大于40%的动脉的敏感性从齐拉计算读数的74%到OPG（K）加CPA联合检查的88%不等。对于直径缩小大于70%的动脉，敏感性从齐拉读数的79%到OPG加CPA联合检查的100%不等。对于直径缩小大于40%的双侧颈动脉疾病，敏感性范围从OPG（Z）的50%到OPG（Z）加CPA的77%不等。
