Abstract
Proton decoupled 13C images were obtained at 2.1 Tesla. 13C{1H} images showed an increase in sensitivity over nondecoupled 13C images because of the nuclear Overhauser effect and elimination of multiple lines from scalar 13C1H spin-spin couplings. The improvement in S N for 13C{1H} images was smaller than expected because of a significant decrease in decoupling efficiency when 13C spin echoes were acquired in a readout gradient. Images of 13C 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 13C{1H} images.
