Abstract
A magnetic imaging device, such as an MR scanner, is used to provide a modified three-dimensional gradient echo sequence having a spatial-spectral excitation in which phase-encoding lines are interleaved for the excitation of water and of fat. The phase-encoding lines are spaced by an interval equal to half of the repetition time. The resulting data are sorted for the reconstruction of water-only and fat-only images, which are realigned and combined to form water-fat combined images free of chemical shift artifacts.
