Abstract
Conventional Magnetic Resonance Imaging (MRI) offers limited sensitivity for direct metabolic and molecular imaging using non-proton nuclei due to low thermal nuclear spin polarization. Hyperpolarization (HP) technologies increase nuclear spin polarization by several orders of magnitude, overcoming this limitation to enable in vivo studies of biochemistry and physiology. A growing body of literature has shown the value in HP technologies offering metabolic and functional information useful for a variety of clinical applications. This review details the complete workflow of hyperpolarized MRI, from the methodologies used to produce hyperpolarized samples and the range of available probes to the specific imaging acquisition and data analysis strategies required to maximize the signal, and finally, its major clinical applications. EVIDENCE LEVEL: 5. TECHNICAL EFFICACY: Stage 3.
期刊介绍：
