in the presense of metal in the body is complicated by B0 field perturbations
and by the shortening of the T2* relaxation times. With a multi-interleave, short readout,
spiral k-space trajectory, chemical shift imaging method, we can image in the
presence of metal. Here we describe a method which can be used in-vitro to
visualize the field maps surrounding metal implants.
