Does common carotid waveform analysis improve the specificity of diagnosing carotid occlusive disease?

Population

150 carotid sides evaluated for carotid occlusive disease

Intervention

Common carotid waveform analysis using the ratio (a-b)/a (difference of frequency from systolic peak to first zero slope after peak systole divided by systolic peak)

Outcome

Specificity in predicting normalcy (distinguishing normal from diseased carotid bifurcation)surrogate

Common carotid waveform analysis using the (a-b)/a ratio can improve the specificity of duplex scanning for carotid occlusive disease to 76%.
