a) The dual-pathway multi-echo pulse sequence employed here is depicted for the case NTE = 4. The 2D version is shown; the 3D version is nearly identical except for the addition of phase-encoding blips along Gz. b) A shorter-TR version of the sequence was also implemented whereby different echo times were obtained by switching the order of the FISP and PSIF echoes on alternate TR periods. The order of the echoes is determined by the size of the pre- and re-phaser pulses, shown shaded. The sequence in (b) was implemented on a GE system with moving table, for motion-related tests, while that in (a) was implemented on Siemens systems.
