In this study, we present the use of multi-contrast delayed enhancement (MCODE) in trouble-shooting regions of high signal intensity within the myocardium that may be atypical delayed enhancement or may simply be blood pool adjacent to the epicardium and trabeculae. Our initial results show the utility of MCODE in clarifying questions of possible delayed enhancement beyond that of myocardial infarction. Furthermore, we demonstrate that a common region adjacent to the anteroseptum that has previously been thought to be blood pool between the septum and right ventricular moderator band or papillary muscle is in fact a tissue-based structure.
