T2-prepared bSSFP sequence consisting of saturation pulses to null the magnetization after each T2-preparation, T2-preparation with composite refocusing pulses in MLEV-4 pattern repeated to achieve TE values of 0, 48, 96, 144 and 192ms at constant interpulse interval (τ180=12ms), and bSSFP encoding with linear ramp-up signal stabilization and partial Fourier sampling.
