Conventional spatial-spectral radiofrequency pulses excite the water or the fat spins in a whole slice or slab. While such pulses prove useful in a number of applications, their applicability is severely limited in sequences with short pulse repetition time due to the relatively long duration of the pulses. In the present work, we demonstrate that, by manipulating the parameters of a two-dimensional spartially-selective (2DRF) pulse designed to excite a two-dimensional spatial profile, the chemical-shift sensitivity of the pulse can be exploited to obtain potentially useful spatially varying fat-water excitation patterns.
