Multi-dimensional spatial selective excitation and parallel transmission have been applied to single- and multi-voxel MR spectroscopy to excite arbitrarily shaped region and shorten the pulse width. Recently the sparse pulse has been developed to shorten the excitation duration by using significantly undersampled k-space. Taking the advantage of this new technique, an example of multi-voxel excitation using sparse pulse is presented. Bloch simulation results demonstrate that each voxel can be well localized within the Field of View and the in-slice error can be controlled within 5%.
