MRI of the heart allows imaging post-infarct myocardial edema -- a key
indicator of area at risk and possibly salvagable tissue. For high-field, 7 Tesla imaging in mice, we
compared composite and adiabatic RF pulses in T2-Prep sequences. By simulation, phantom and in vivo imaging,
we developed a flexible adiabatic T2-Prep method for whole-heart imaging of
myocardial edema from onset within hours through resolution past the 20 day
point.
