Simulation of Contrast Agent Transport in Arteries with Multilayer Arterial Wall: Impact of Arterial Transmural Transport on the Bolus Delay and Dispersion

Figure 6

Effects of disturbed flow on contrast agent transport. (a) Concentration distribution in the stenosed region at three time points of the contrast injection at the inlet. is the moment with half maximal concentration in the increasing phase; is the moment with maximal concentration; is the moment with half maximal concentration in the decreasing phase.
