Flow patterns in low-degree stenosis. a) B-mode demonstrates atherosclerotic thickness (short arrows) and a rose thorn minor plaque (arrowhead). b) CD shows a limited area of increased velocity (*). PW excludes a relevant PSV (99 cm/s) and spectral broadening (arrowhead). c) VFI shows aminar flow before the plaque (arrow), layers detachment from the boundary (short arrow), eccentric max velocity vectors (arrowhead) and large complex flow (*) along the opposite wall.
