From: High-frame rate vector flow imaging of the carotid bifurcation
Flow assessment in kinked ICA (angle ≈90°). a) CD shows a mosaic of colors—aliasing artifact (*). b) Power Doppler outlines the lumen reduction (arrow), without any quantification. PW bidirectional flow (arrowhead) and spectral broadening (*) highlight the turbulence. c) VFI quantifies the stricture by showing high-velocity red vectors (short arrow) and strong vorticity (*). CCA = Common carotid artery. ICA = Internal carotid artery. ECA = External carotid artery
