Reorientation and sampling of myocardial ROI, metabolite-corrected blood input functions and myocardial TACs, and MBFi K 1 polar-maps. (A) Reorientation and sampling of the myocardial region of interest (ROI) in the transverse, vertical long-axis, and horizontal long-axis planes (FlowQuant© software). The image-derived input function (IDIF) from the inferior vena cava (VC) blood region (red) was created semi-automatically. (B) Metabolite-corrected blood input functions and myocardial TACs at rest and stress. (C) Myocardial blood flow index (MBFi) K1 polar-maps derived using the inferior VC blood input at Rest, low-dose salbutamol Stress, and stress/rest (Flow Reserve).
