Key result
A color-coded continuous-wave Doppler scanner demonstrated 71% sensitivity and 82% specificity for diagnosing carotid lesions with greater than 50% stenosis compared to arteriography.
Why the study?
Does a color-coded continuous-wave Doppler scanner with real-time frequency analysis accurately diagnose carotid lesions with >50% stenosis compared to arteriography?
Population

May support noninvasive carotid screening; leaves open need for prospective validation before replacing arteriography.

Does a color-coded continuous-wave Doppler scanner with real-time frequency analysis accurately diagnose carotid lesions with >50% stenosis compared to arteriography?
A color-coded continuous-wave Doppler scanner combined with real-time frequency analysis provides moderate sensitivity and good specificity for diagnosing significant carotid stenosis.
Johnston et al. (1981) conducted an observational in Carotid disease. Color-coded continuous-wave Doppler scanner and real-time frequency analysis vs. Arteriography was evaluated on Diagnosing carotid lesions with greater than 50% stenosis. A color-coded continuous-wave Doppler scanner demonstrated 71% sensitivity and 82% specificity for diagnosing carotid lesions with greater than 50% stenosis compared to arteriography.
