The 13C singlet lifetime of [1,2-13C2]pyruvate is significantly longer than the 13C T1 in human blood and in a mouse in vivo at millitesla fields. The singlet-derived NMR spectrum observed for hyperpolarized [1,2-13C2]lactate, originating from the metabolism of [1,2-13C2]pyruvate, is also examined.
