Computational Fluid Dynamics Simulations of Contrast Agent Bolus Dispersion in a Coronary Bifurcation: Impact on MRI-Based Quantification of Myocardial Perfusion

<table>Top: velocity magnitude in the bifurcation region for hyperemia at the time step of maximum velocity for pulsatile flow. Bottom: axial velocity inside the stenotic LAD for the case of hyperemia at the time step of maximum velocity for pulsatile flow. The LAD branches are scaled by a factor of 1.5 in radial direction for better visualization. Axial velocity profile along a radial line (red arrow) directly behind the bifurcation is presented (middle, left).</table>
