Representative FPP images and corresponding late gadolinium enhancement (LGE) images in canine models of myocardial infarction (MI). (a1,b1): images correspond to a chronic MI dog study that shows small subendocardial LGE (a) and FPP defect in the lateral wall. The defect is clearly seen demonstrating the ability of the proposed method to resolve small defects (following apodization). (a2,b2) Similar result with a larger defect region in an acute MI dog. (a3,b3): images for a control animal study. All images correspond to the peak myocardial enhancement phase. Among the 3 studies, minimal DRA is seen in only (b2) and (b1,b3) are free of DRA. The results demonstrate that reduction of subendocardial DRAs using apodization (applied to a high-resolution scan) does not lead to elimination/masking of subendocardial defects in the reconstructed apodized images.
