Abstract

The design of an RF probe suitable for obtaining proton‐decoupled ^13^C spectra from a subhuman primate brain is described. Two orthogonal saddle coils, one tuned to the resonant frequency of ^13^C and the other to the resonant frequency of ^1^H, were used to monitor the in vivo metabolism of [1‐^13^C] glucose in rhesus monkey brain at 2.1 T. Difference spectra showed the appearance of ^13^C‐enriched glutamate and glutamine 30 to 40 min after a bolus injection of [ 1‐ ^13^C] glucose.
