¨ABSTRACT: NMR imaging has been shown to be a viable and useful approach to exploring spatial chemistry and molecular dynamics of a wide range of materials. NMR provides image contrast which is fundamentally different from that of other methods. The principles of NMR imaging and spatial information

Basic filters are described for preparation of magnetization in imaging. The filters are based on relaxation times, chemical shift selectivity, field distortions from susceptibility differences, and on relaxation during multipulse excitation for manipulation of the dipole ᎐ dipole interaction in sol
