Proton decoupled /sup 13/C images were obtained at 2.1 Tesla. /sup 13/C(1H) images showed an increase in sensitivity over nondecoupled /sup 13/C images because of the nuclear Overhauser effect and elimination of multiple lines from scalar /sup 13/C-1H spin-spin couplings. The improvement in S/N for /sup 13/C(1H) images was smaller than expected because of a significant decrease in decoupling efficiency when /sup 13/C spin echoes were acquired in a readout gradient. Images of /sup 13/C compounds that had a wide range of chemical shifts showed separated and/or overlapping images, which is consistent with chemical shift imaging artifacts seen in 1H images. This work examines the technical constraints of acquiring and the difficulties of interpreting /sup 13/C(1H) images.
