Abstract
It is demonstrated that the resolution of the (1)H NMR metabolite spectrum in a live mouse can be significantly enhanced by an ultraslow magic angle spinning of the animal combined with a modified phase-corrected magic angle turning (PHORMAT) pulse sequence. Proton NMR spectra were measured of the torso and the top part of the belly of a female BALBc mouse in a 2 T field while spinning the animal at a speed of 1.5 Hz. It was found that even in this relatively low field, with PHORMAT an isotropic spectrum is obtained with line widths that are a factor of 4.6 smaller than those obtained in a stationary mouse. It is concluded that in vivo PHORMAT has the potential to significantly increase the utility of (1)H NMR spectroscopy for biochemical and biomedical animal research.
