Key result
Continuous-wave Doppler ultrasound imaging yielded a 56% false negative and 19% false positive rate compared to arteriography for detecting carotid artery stenosis.
Why the study?
Does continuous-wave Doppler ultrasound imaging accurately predict arteriographic abnormality at the carotid bifurcation compared to arteriography?
Population
105 patients (195 arteries) undergoing evaluation of the carotid bifurcation
Comparison
Continuous-wave (CW) Doppler ultrasound imaging vs Arteriography (angiography)
Design
Cross-sectional

High false-negative rates limit continuous-wave Doppler reliability for carotid stenosis; leaves open validation of modern noninvasive imaging against arteriography.

Does continuous-wave Doppler ultrasound imaging accurately predict arteriographic abnormality at the carotid bifurcation compared to arteriography?
Continuous-wave Doppler ultrasound provides supplementary information but has high false negative rates and cannot substitute for arteriography in evaluating carotid bifurcation stenosis.
Weaver et al. (1980) conducted an observational in Carotid artery abnormality (n=105). Continuous-wave (CW) Doppler ultrasound imaging vs. Arteriography was evaluated on Prediction of arteriographic abnormality. Continuous-wave Doppler ultrasound imaging yielded a 56% false negative and 19% false positive rate compared to arteriography for detecting carotid artery stenosis.
