Principle behind 3-dimensional (3D) plaque assessment on T1-weighted imaging. Gray cubes represent voxels. αn represents the signal intensity of each voxel with higher signal intensity than that of nearby myocardium. Entire voxels of a coronary plaque that are above the signal intensity of nearby myocardium (plaque-to-myocardial signal intensity ratio > 1.0) were segmented within contiguous slices (surrounded by yellow dotted lines) to calculate the integral of signal intensity and voxel volume
