Storage of magnetization as singlet order by optimal control designed pulses
Laustsen C, Bowen S, Sloth Vinding M, Chr Nielsen N and Ardenkjaer-Larsen JH2014
ccccThe use of hyperpolarization to enhance the sensitivity of MRI has so far been limited by the decay of the polarization through T1 relaxation. Recently, methods have been proposed that extend the lifetime of the hyperpolarization by storing the spin order in slowly relaxing singlet states.
