Carbon-13 (13C) MR spectroscopy (MRS) requires RF coils enabling acquisition at two different Larmor frequencies, namely at the 1H frequency (f1H=297.2 MHz) for scout imaging, B0 shimming and proton decoupling, as well as at the 13C frequency (f13C=74.7 MHz) for acquisition of the carbon spectra at 7T. In this work we present preliminary data on the development of a dual tuned 13C/1H coil array for calf muscle studies at 7 T, including simulation, bench and MR measurements in a glucose phantom.
