Radical-free hyperpolarized MRI using endogenously occurring pyruvate analogues and UV-induced nonpersistent radicals

Rolf Gruetter, Andrea Capozzi, Josefina Adriana Maria Bastiaansen, Hikari Ananda Infinity Yoshihara, Alice Radaelli, Claudia Christina Zanella, Lionel Pierre Arn

It was recently demonstrated that nonpersistent radicals can be generated in frozen solutions of metabolites such as pyruvate by irradiation with UV light, enabling radical-free dissolution dynamic nuclear polarization. Although pyruvate is endogenous, the ...
