A complex duplex carotid evaluation involves high resolution imaging and characterization of the carotid plaque as well as quantitative Doppler spectral analysis to determine the presence and degree of flow restriction. Each of the components of the examination is essential to evaluate the carotid arteries adequately for the presence of disease. Both of these components should be assimilated into a final report that can be used to determine who is at risk for embolic as well as flow restrictive disease. By carefully following the reporting system described in this paper, an accurate and reproducible means of evaluating the carotid arteries can be achieved that permits comparison of studies. In addition, this will allow accurate communications among institutions and help to insure a better understanding of the etiology and pathogenesis of atherosclerotic carotid artery disease.
