Carbon-13 (¹³C) MR spectroscopy (MRS) requires RF coils enabling acquisition at two different Larmor frequencies, namely at the¹H frequency (f_1H=297.2 MHz) for scout imaging, B₀ shimming and proton decoupling, as well as at the ¹³C frequency (f_13C=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.
