✦ Synopsis

We propose a family of hybrid chemical-shift sequences which combines two physical principles for water/lipid separation to minimize artifacts introduced by Bo and B , inhomogeneities. Hybrid sequences provide improved species discrimination over earlier methods without resorting to postprocessing while maintaining a multislice/multiecho capability.

The hybrid technique of projection-reconstruction echo-planar (PREP) imaging for obtaining chemical-shift images is demonstrated experimentally using a fluorine sample. The technique which is a variation on echo-planar imaging (EPI) relies on a multipass procedure. It is nevertheless quite efficient

Selective suppression of a given resonance in an NMR image can be obtained with a i ~/ 2 pulse whose excitation spectrum is zero at the appropriate chemical shift. The selective 7r/2 pulse presented here is composed of two nonselective i ~/ 2 pulses of opposite phase. The two pulses are separated by

The phase-encoded echo-planar (PEEP) technique, a variant of echo-planar imaging, is used to achieve simultaneous high-speed spatial and chemical-shift data acquisition. This technique is the 2DFT equivalent of the projection reconstruction echo-planar method for chemical-shift imaging. Examples of
