A Anterior and posterior views of the heart 3D anatomy showing the extraction of the vessel-specific myocardium subtended to the LAD, LCX and rPDA and their discretization in ROIs for dPET sampling and TAC extraction. B Comparison between the manual LAD vessel-specific ROIs (red) and the fully automated ROIs (blue) with their corresponding centerlines. C same as in B comparing manual (red) and corrected (orange) LAD ROIs. M manual, FA fully automated. C corrected. ROI region of interest, LAD left anterior descending artery, LCX left circumflex artery, rPDA right posterior descending artery, TACs time activity curves
