In vivo magnetic resonance elastography to estimate left ventricular stiffness in a myocardial infarction induced porcine model

Purpose To estimate change in left ventricular (LV) end‐systolic and end‐diastolic myocardial stiffness (MS) in pigs induced with myocardial infarction (MI) with disease progression using cardiac magnetic resonance elastography (MRE) and to compare it against ex vivo mechanical testing, LV circumfer...
