Hyperpolarized magnetic resonance is a non-toxic, non-radioactive method for assessing tissue metabolism and other physiologic properties. Hyperpolarization allows for over 10,000-fold signal enhancement relative to conventional magnetic resonance imaging (MRI) or spectroscopy (MRS). My laboratory has worked on three different modalities of hyperpolarization, both on technique development as well as advancing novel in vivo applications. The research described here is focused on the different in vivo applications of Parahydrogen Induced Polarization (PHIP) (and subsequent transfer to 13C), continuous flow Dynamic Nuclear Polarization (DNP) of water (1H), and long lived DNP hyperpolarized signal of Silicon nanoparticles (29Si) as molecular imaging agents.
