Myocardial fat content, R2*/T2* and off-resonance frequency can be measured with high resolution using a native MR water-fat separation imaging technique applied to multiple gradient echo images. Significant differences in myocardial fat fraction were found consistent with fatty metaplasia in a subset of chronic myocardial infarction patients. Off-resonance and T2* changes consistent with intramyocardial hemorrhage were observed in a subset of acute myocardial infarction patients.
