The individual and combined diagnostic accuracy rates for fluid-filled oculoplethysmography and pulsed Doppler ultrasonic imaging in the detection of extracranial carotid artery insufficiency were calculated. Results of the two techniques were compared with those of contrast arteriograms which were available for 109 patients, 210 arteries, for computations of sensitivity and specificity. Sensitivities for oculoplethysmography and ultrasonic imaging were 84 and 87 per cent, while specificities were 87 and 81 per cent, respectively. These values were not significantly, p greater than 0.05, different. Results of oculoplethysmography and ultrasonic imaging agreed in four-fifths of the arteries, producing a sensitivity of 98 per cent and a specificity of 97 per cent. In the remaining arteries, the results of the two tests did not agree, resulting in a sensitivity of 71 per cent and a specificity of 79 per cent. Fluid-filled oculoplethysmography and pulsed Doppler ultrasonic imaging are diagnostic tests of comparable accuracy which, when used together, provide accurate hemodynamic and anatomic information in the diagnosis of extracranial carotid arterial disease.
计算了用于检测颅外颈动脉供血不足的液体填充式眼体积描记法和脉冲多普勒超声成像的个体诊断准确率及联合诊断准确率。将这两种技术的结果与109例患者、210条动脉的动脉造影结果进行比较，以计算敏感性和特异性。眼体积描记法和超声成像的敏感性分别为84%和87%，而特异性分别为87%和81%。这些值差异不显著，p大于0.05。眼体积描记法和超声成像在五分之四的动脉中结果一致，敏感性为98%，特异性为97%。在其余动脉中，两种检测结果不一致，敏感性为71%，特异性为79%。液体填充式眼体积描记法和脉冲多普勒超声成像的诊断准确性相当，联合使用时能在颅外颈动脉疾病诊断中提供准确的血流动力学和解剖学信息。
