Phased spectroscopic images: application to the characterization of the 1H 1.3-ppm resonance in intracerebral tumors in the rat.
Spectra obtained with phase-encoding techniques show phase-shifts varying from voxel to voxel. The procedure allowing voxel-dependent phase-shifts to be compensated is presented. The method has been applied to the characterization of the 1.3-ppm resonance observed in intracerebral tumors in the rat.
