Hyperpolarized 13C enhances the SNR of signals from 13C metabolites. Separate transmit and receive coils are inserted into the magnet bore to image 13C, limiting patient space. Here, a dual tuned 13C /1H body coil is developed that is capable of imaging both proton and 13C in one exam. The coil has the same 70 cm inner diameter as the standard body coil and can be used stand-alone as the Tx/Rx coil, or as the transmit coil for proton and 13C receive arrays. The efficiency for proton excitation is comparable to that of the standard proton only body coil.
