Figure 4:

Bloch simulation—including the impacts of the RF pulses—of the echo train. The simulation assumes the T₁ and T₂ values of muscle at 3.0T (T₁ = 1300 ms and T₂ = 32 ms). The initial phase is the phase of the first 90° pulse of the magnetization preparation module. By using a more aggressively tailored refocusing RF train and by spoiling the non-MG component of the signal prior to the CPMG echo train, the ss-MGOT approach provides improved signal stability.
