Fat-water swapping artifact

Fat-water swapping artifact is seen in a significant proportion of fat/water suppressed sequences using the Dixon method. The artifact follows a computational error in areas of field inhomogeneity resulting in incorrectly determining whether a voxel contains water or fat.

The images have geographic regions of inappropriate suppression with sharp margins. It can be seen anywhere but is most striking when a whole solid organ appears black on suppressed images.
