A flexible torso ¹³C RF coil with quadrature transmit and 8-channel receive array that is designed for imaging cardiac and hepatic metabolism in humans was evaluated. B₁⁺ field homogeneity and SNR were measured using phantoms. The torso coil had improved SNR and larger spatial coverage as compared to the conventional clamshell/paddle array coils.
