Plot of Stress Perfusion (Flow) and CFR for Each of 1,344 Perfusion Pixels of LV
Plot determining unique, unequivocal color code for stress perfusion and CFR for each pixel that is back-projected onto coronary flow capacity map with histogram for percentage of all pixels in LV in each color-coded range of stress flow and CFR of each pixel. For illustration, only lateral views of stress flow and CFR are shown, and a single pixel is tracked through the pixel color-coding process. Quadrant mean perfusion values are calculated as average of all pixels in that quadrant. Global perfusion is calculated as average of all pixel values in the LV. CFR = coronary flow reserve; LV = left ventricle.
