Dixon water/fat separation sequences usually need at
least two images acquired at different TEs constrained
to specific values, causing prolonged repetition and
acquisition times and complicating application in
dynamic imaging (e.g. DCE-MRI). We propose a single
point water/fat separation method based on alternation
of two RF pulses that introduces a spatial shift of fat
with respect to water in the reconstructed image. We
demonstrate the feasibility of this method and obtain
in-phase water/fat separated images at an arbitrary echo
time in a single acquisition.
