Type
II diabetic patients suffer from higher susceptibility to develop post
myocardial infarction (MI) heart failure. By adapting a self-gated FLASH to a
murine model of the diabetic heart, we obtained multiple slices of the left
ventricle and assessed changes in cardiac physiology post MI. Diabetic MI
mice displayed decreased cardiac contractility and increased end-systolic
volume, while non-diabetic MI mice presented increased end-diastolic volume
with preserved ejection fraction. These data suggest that imaging of murine
hearts is achievable using a self-gated FLASH, and the results are accurate
enough to detect differences in functional analysis between genotypes and interventions.
