A. Voxel view of spin dephasing. Spins with different off-resonance will gain different amounts of phase during signal readout leading them to “fan out”, and eventually completely cancel each other. B. A gradient echo image is shown for two different slices at three different echo times (TE). At the later echo times, signal loss due to dephasing is present as indicated by the arrows.
