Plot of T2 and extracellular volume (ECV) values for subjects with Duchenne muscular dystrophy. A) Global T2 and ECV; B), C), and D)T2 and ECV of the inferior, inferolateral and anterolateral segments, respectively. Cut-offs are 2 standard deviations above the mean for control subjects. Values in yellow shading represent increased ECV and normal T2 suggestive of fibrosis, while values in blue represent increased T2 and normal ECV, suggestive of edema. Values in white represent "normal" myocardium without extracellular matrix expansion, while values in green either represent edema or a combination of edema and fibrosis.
