Modeling of the Renal Kinetics of the AT1 Receptor Specific PET Radioligand [¹¹C]KR31173

Figure 6

Compartmental curve fits of time-activity curves (a) and impulse response function (b). Visually both the TACs and the impulse response functions appear biexponential. In the compartmental model the fit is excellent for each kidney with both approaches.
