PROTON SPECTROSCOPIC IMAGING IN THE SOLID-STATE BY TREV-CRAMPS

A spatial-spectral H-1 NMR imaging approach, based on line narrowing by TREV-CRAMPS, is presented for samples rotating under magic-angle spinning (MAS). Phase encoding of spatial information along one axis (the MAS rotor axis in the present case) is achieved by suitable application of gradients during specific segments of the TREV-8 pulse sequence applied during an evolution period. Chemical-shift information is frequency encoded during data acquisition under the TREV-8-CRAMPS sequence. Examples are shown for solid phantoms. (C) 1994 Academic Press, Inc.
