Spatial encoding has been integrated into a J-resolved spectroscopic sequence, resulting in a technique capable of acquiring 2D spectroscopic data over a 2D spatial array. A Multi-Echo based acquisition scheme was applied to the sequence to accelerate the acquisition rate. The viability of this sequence was demonstrated by acquiring five scans of a brain metabolite phantom with an 8-channel knee-array coil. The resulting spectra showed peaks due to a variety of metabolites at physiological concentrations and each produced a spherical spatial profile consistent with the shape of the brain phantom.
