Fig 3. RMS Errors in estimated T2 vs SNR for various FSE methods.

Fig 3

Legend keys refer to the acquisition trajectory (EP or VT) and the fitting model (EPG or exponential, EXP). EXP fits were applied to data refocused using 170–190° pulses; all others were applied to 110–130° refocused data. As SNR increases, ME-CAMBREC and other accelerated protocols approach a lower error limit due to estimate bias. In practice, ME-CAMBREC demonstrates better T2 accuracy than most Fourier-reconstructed methods at both high and low SNR.
