Abstract
A method and system for providing prelocalization of a volume of interest and for rapidly acquiring a data set for generating spectroscopic images. Spatial prelocalization of a volume of interest is achieved by providing a presuppression sequence before a stimulated echo (STE) sequence and a suppression sequence during the mixing time (TM) interval of the STE sequence. The presuppression sequence includes a spatial suppression sequence to selectively saturate slices that intersect the plane selected by the STE sequence in order to define a boundary for the volume of interest, and this spatial suppression sequence is substantially repeated during the TM interval of the STE sequence. Spectroscopic imaging data is acquired by an oversampled echo planar spatial-spectral imaging sequence in which the gradient reversal frequency is a integer factor of n greater than the gradient reversal frequency required to sample the spectral width.
