Abstract

This chapter introduces the physical principles underlying hyperpolarized (HP) gas magnetic resonance. The properties of such HP gases, including spin I?1/2 noble gas isotopes and low molecular-mass gases like propane, are introduced in the context of biomedical applications. Of particular interest are mechanisms of relaxation and contrast, and the ramifications of using HP gases in magnetic resonance imaging studies. The primary technologies for producing such HP gases are also introduced and described, including spin-exchange optical pumping (SEOP), metastability-exchange optical pumping (MEOP), "brute-force" polarization (BFP), dynamic nuclear polarization (DNP), and parahydrogen-induced polarization (PHIP). The advantages, limitations, and outlooks for such approaches are discussed.
