Model-corrected blood input function (MCIF). (A) Representative 2-[18F] fluoro-2-deoxy-D-glucose positron emission tomography (FDG PET) images with regions of interest drawn in the myocardium and (B) left ventricular blood in the last time frame. (C) Dual-output model (Model IDIF, Model Myo) fitted to image-derived blood (PET IDIF) and myocardium (PET Myo) time activity curves (TACs) to generate the MCIF. For comparison, blood samples derived from arterial blood sampling are shown.
