FIGURE 4. Agreement between regional wall motion scores per segment on MRI and on gated 18F-FDG PET. Basal segments: 1 = anterior; 2 = lateral; 3 = inferior; 4 = septal. Distal segments: 5 = anterior; 6 = lateral; 7 = inferior; 8 = septal. 9 = apical segment. Mean = mean agreement for all 9 segments ± SEE.
