Flow patterns in hemodynamically relevant stenosis. a) B-mode and CD of the ICA sinus demonstrates a short plaque (arrowheads) causing severe stenosis: CD depicts a mixture of high velocities and directions (*), distally to the stenosis. b) VFI shows high-velocity vectors bundled (arrowheads) while entering the stenosis. Distally, turbulent flow coded by green/orange vectors, randomly oriented, and by reversed red vectors (short white arrow). Blue dot (void arrow): max velocity point. CCA = Common carotid artery. ICA = Internal carotid artery
