Hyperpolarized-13C substrates have become a promising tool to study real-time cardiac-metabolism in-vivo. Multi-channel receiver systems can provide similar SNR performance to a single surface coil, but with increased coverage. A single channel and a 5-channel array 13C receive coil were simulated in Matlab and compared with in-vivo measurements. SNR improvements at the base of the heart, were achieved by using the 5-channel coil array. This coil array may be suitable for human cardiac 13C studies and parallel imaging reconstruction in the near future.
