Delayed enhancement images (a, b) and myocardial extracellular volume (ECV) polar maps (c, d) of a control subject and a hemodialysis (HD) patient. No focal area of delayed enhancement is detected in the control subject (a) or HD patient (b). The myocardial ECV polar map of the control subject (c) shows normal myocardial ECV. The myocardial ECV polar map of the HD patient (d) shows higher ECV, indicative of advanced myocardial fibrosis that is undetectable from the delayed enhancement image (b). In the polar maps, ECV values are displayed as fractions.
