Simultaneous multi-slice excitation in spatially encoded NMR experiments

A novel strategy to enhance the experimental sensitivity in spatially encoded NMRexperiments is presented. The use of a multiple-frequency modulated pulse applied simultaneously to an encoding gradient can afford a substantial sensitivity gain with respect to single-slice selected experiments. The z-dependent position of each individual proton resonance allows the choice of a determined number of complementary k offsets that allows parallel data collection for a specific proton in multiple parts of the NMR tube whereas other mutually J-coupled protons are not excited into the same slice. The experimental set-up protocol to fulfill the sampled frequency requirement is simple and the results can be inmediately adapted to a wide range of applications.
