Figure 5From: Physiologically based pharmacokinetic modeling of arterial – antecubital vein concentration differenceComparison of DTPA PBPK model arterial (red line) and antecubital vein (blue line) concentrations with the experimental data (squares) of Cousins et. al. [10] (top panel). The bottom panel compares the model antecubital vein/arterial concentration ratio (black line) versus the experimental values (squares). Using a fractional contribution of muscle to antecubital vein blood of 0.05.Back to article page
