Computational Fluid Dynamics Simulations of Contrast Agent Bolus Dispersion in a Coronary Bifurcation: Impact on MRI-Based Quantification of Myocardial Perfusion
Mass fraction of the contrast agent as a function of time for pulsatile flow under resting condition for limited autoregulation. The positions of the respective cross sections are marked in Figure 1(b). The small oscillations of the contrast agent mass fraction at the outlets are caused by the pulsatile flow.
