Does pulsed Doppler spectral analysis accurately detect extracranial carotid disease compared to arteriography?
Pulsed Doppler spectral analysis is highly accurate for detecting significant extracranial carotid disease and occlusions compared to arteriography.
Russell et al. (1984) studied this question. Pulsed Doppler spectral analysis correctly detected all carotid occlusions, normal vessels, and stenoses >25%, and 43% of stenoses <25%, compared to arteriography in 224 arteries.
