Dennis F. Bandyk (1985) conducted an observational in Carotid Bifurcation Disease (n=122). Quantitative Doppler Spectrum Analysis vs. Contrast arteriography was evaluated on Agreement with angiography in classifying internal carotid artery stenosis. Quantitative Doppler spectrum analysis demonstrated 82% agreement with contrast arteriography in classifying internal carotid artery stenosis and identified 96% of hemodynamically significant disease.
