Why the study?
Can a pulsed Doppler velocimeter detect differences in volume blood flow and velocity profiles between normal and diseased common carotid arteries?
Population
100 common carotid arteries in man (50 normal and 50 diseased)
Comparison
Measurement of volume blood flow and velocity… vs Angiographic description (for diseased arteries)
Design
Cross-sectional

May support noninvasive carotid assessment; leaves open prospective validation against velocity profiles and outcomes.
Can a pulsed Doppler velocimeter detect differences in volume blood flow and velocity profiles between normal and diseased common carotid arteries?
Pulsed Doppler velocimetry can detect early disturbances in velocity profiles in diseased carotid arteries before significant changes in volume flow or angiographic appearance occur.
Fitzgerald et al. (1982) studied this question.
