IMAGING AGENTS AND METHODS OF USE THEREOF

摘要

Compositions and methods useful in connection with magnetic resonance imaging are provided. Metabolites hyperpolarized by dynanic nuclear polarization are used as reporter molecules in nuclear magnetic resonance ("NMR") spectroscopy to study metabolic pathways and diagnose disease states. The reporter molecules include hyperpolarized glutamine and hyperpolarized acetate. The invention includes the reporter molecules, compositions including the reporter molecules in pharmaceutically acceptable carriers, methods for studying metabolic pathways that include introducing one or more of the reporter molecules to a mammalian subject and imaging a target substance using NMR spectroscopy, and kits useful in studying metabolic pathways that incorporate one or more of the reporter molecules and instructions for their use.
