ABSTRACT:
A multiple quantum excitation pulse sequence for producing NMR signals is optimized for reconstructing images of the distribution and levels of metabolites in vivo using magnetic field gradients. Unwanted signals from water are reduced by application of composite magnetic field gradients, unwanted signals from lipids are reduced by use of a frequency selective pulse optimized to null the lipid signals, and the signal-to-noise ratio of the signals produced by lactate are enhanced by the addition of two 180.degree. excitation pulses to the sequence.
