Key result
The Hokanson-pulsed Doppler ultrasonic arteriograph achieved a sensitivity of 86% and specificity of 90% for detecting carotid stenosis, compared to 64% and 85% with oculoplethysmography.

Does the Hokanson-pulsed Doppler ultrasonic arteriograph or Kartchner-McCrae oculoplethysmograph accurately diagnose extracranial carotid arterial disease compared to roentgenographic studies?
Absolute Event Rate: 86% vs 64%
The pulsed Doppler ultrasonic arteriograph is more sensitive and specific than the oculoplethysmograph for noninvasive diagnosis of carotid artery stenosis, though combining both tests yields the highest accuracy when they agree.
David S. Sumner (1979) conducted an observational in Extracranial Carotid Arterial Disease (n=200). Hokanson-pulsed Doppler ultrasonic arteriograph (UA) vs. Kartchner-McCrae oculoplethysmograph (OPG) was evaluated on Sensitivity for detecting carotid artery stenosis compared to roentgenographic studies. The Hokanson-pulsed Doppler ultrasonic arteriograph achieved a sensitivity of 86% and specificity of 90% for detecting carotid stenosis, compared to 64% and 85% with oculoplethysmography.
