Who Needs Directions? Interpreting, Standardizing, and Teaching Doppler Direction

Darrin Cournoyea

Darrin Cournoyea. How can a single direction of flow be displayed with two separate colours? When should venous flow be displayed above the spectral Doppler graph baseline? How do I help my student or junior sonographers interpret flow direction with both colour and spectral Doppler? These questions plus a few more will be answered in this discussion on the sometimes confusing concept regarding the display of blood flow direction in diagnostic Doppler sonography.
