Metabolite images are produced with an MRI system using a priori information about the resonant peaks of the metabolites and their relative sizes to reduce the amount of NMR data needed for proper spectral resolution. With the a priori information the acquired NMR signal is modeled. Using this model and NMR data acquired at a plurality of echo times (TE), the metabolite at each image pixel is calculated.
