Non-invasive examination of 431 vessels in 333 patients with cerebrovascular disease in all stages was performed in order to compare the reliability of the periorbital Doppler test alone and together with the more difficult insonation of the carotid arteries in the neck (combined Doppler). These findings were compared with those of subsequent arteriography. Extracranial obstructive (greater than 50%) carotid disease was detected with 100% sensitivity by the combined Doppler, but with only 48% sensitivity by the periorbital indirect test. The specific ability of both methods to identify non-stenotic carotid arteries (less than 50%) was similar at about 98%. Only the combined Doppler examination reliably differentiated various degrees of obstruction, comparable to that obtained with arteriography. Non-obstructive plaques could not be detected or excluded by either Doppler test. More refined methods will be necessary for their evaluation.
为了比较单独眶周多普勒检查以及联合难度较大的颈部颈动脉超声检查（联合多普勒检查）的可靠性，对333例处于各个阶段的脑血管疾病患者的431条血管进行了无创检查。将这些结果与随后的动脉造影结果进行比较。联合多普勒检查对颅外阻塞性（大于50%）颈动脉疾病的检测灵敏度为100%，而眶周间接检查的灵敏度仅为48%。两种方法识别非狭窄性颈动脉（小于50%）的特异度相似，约为98%。只有联合多普勒检查能够可靠地区分不同程度的阻塞，与动脉造影结果相当。两种多普勒检查均无法检测或排除非阻塞性斑块。对其进行评估需要更精细的方法。
