Cardiac MRI (CMR) based staging of myocardial infarction (MI) with or without contrast agents relies on the resolution of edema in the chronic phase, which is typically determined on the basis of T2-based MRI. However, whether T2 CMR is sufficient for staging all MI types has not been studied. We investigated this using animal models with and without hemorrhagic MIs. Our results show that non-hemorrhagic MIs can be staged based on T2 changes in the MI territory. However, the incomplete resolution of T2 elevations in the peripheral layers of hemorrhagic MI territories can confound staging of hemorrhagic MIs.
