2D plots of stress, rest \({\text{MBF}}_{{{\text{FA}}}}^{{{\text{vs}}}}\) (magenta), \({\text{MBF}}_{{\text{C}}}^{{{\text{vs}}}}\) (green) and \({\text{MBF}}_{{\text{M}}}^{{{\text{vs}}}}\) (blue) from the base to the apex in mm for the LAD, LCX and rPDA of one of the analyzed cases. The flow values profiles are compared to previously developed r/s MBFvs ranges for patients with low risk of CAD (grayed area). Vessel-specific ROI values indicated with markers (*); continuous curves obtained by interpolation. For the displayed case, stress (rest) FA Dice coefficients were for LAD, LCX and rPDA, respectively, 0.96, 0.86 and 0.94 (0.96, 1.00 and 0.94); and stress (rest) C Dice coefficients were, respectively, 0.96, 0.86 and 0.96 (0.96, 1.0 and 1.0). ROI region of interest, LAD left anterior descending artery, LCX left circumflex artery, rPDA right posterior descending artery
