Patterns of delayed enhancement are different in dilated cardiomyopathy and ischemic cardiomyopathy, reflecting the presence of scarring or various degrees of fibrosis in left ventricular myocardium. The presence of subendocardial or transmural delayed enhancement at contrast-enhanced cardiovascular magnetic resonance allowed distinction between dilated cardiomyopathy and ischemic cardiomyopathy with high sensitivity (88%) and specificity (100%).
