ABSTRACT:
Techniques for conducting two-dimensional fat-saturated multislice MR studies are disclosed. The frequency of saturation pulses is varied on a slice-by-slice basis. In a second preferred embodiment, the phase, or the phase and frequency, of one or more elements of a spatially and spectrally selective MR pulse sequence are varied on a slice-by-slice basis. In a third preferred embodiment, the order in which MR image data is acquired from a plurality of slices is changed so as not to minimize the time between inadvertent saturation of the water signal in a particular slice and the acquisition of MR image data from that slice.
