SNR of [1-13C]lactate from kidney ROI vs concentration of unlabeled sodium lactate in dissolution buffer of injected [1-13C]pyruvate in rats H199, H322 and H326. Linear trend lines are indicated. Under these conditions, the x = 0 intercept is related to the amount of lactate exchange and flux generated 13C labeling at steady state.
