GLP-1r binding potential expressed as a distribution volume of specific binding (Vs expressed in mL/ccm) obtained after fitting of the [68Ga]Ga-DO3A-VS-Cys40-exendin-4 uptake to a 2-tissue compartment model in both the fasted state and during the plateau phase of a hyperinsulinemic–euglycemic clamp
