Location representation of regions of interest (ROIs) based on the American Heart Association 17-segment model for myocardial segmentation. [37] Shading indicates percentage of native T1 values in that segment that were abnormal (> 1050). In basal slices, ROIs were generated on two septal segments each (segment 2 and 3) and a lateral wall region (combined segments 5 and 6). In mid slices, ROIs were generated on two septal segments each (segment 8 and 9) and a lateral wall region (combined segments 11 and 12). In apical slices, ROIs were generated on the septal (segment 14) and lateral (segment 16) segments. Of note, per lab standard, anterior and inferior segments were not analyzed to avoid partial volume effect
