Most in vivo studies using the dynamic nuclear polarization technique to enhance sensitivity of 13C have been utilizing molecules with 13C labeled quaternary carbons. These carbons possess small long-range J-couplings with protons. Here we show that, although 1H-decoupling has little impact on the [1-13C]pyruvate resonance it significantly improves the linewidth and SNR of [1-13C]lactate, [2-13C]pyruvate and [2-13C]lactate.
