The change in (a) signal differences and (b) contrast ratios between edematous and normal myocardium with TEprep in T2STIR-balanced steady state free precession (bSSFP) and T2p-bSSFP in simulation. The signal differences are defined in normalized units of equilibrium magnetization (M0). The contrast ratio of T2 value between edematous and normal myocardium is also shown for comparison. T2STIR-bSSFP has a higher signal difference than T2p-bSSFP and has the highest contrast ratio among the three edema imaging sequences. The contrast ratios from T2p-bSSFP and the T2 map are similar, as both were T2-prepared in the same way. The contrast ratio of T2STIR-bSSFP increases faster with TEprep than that of T2p-bSSFP
