Hyperpolarized ¹³C MR imaging provides valuable enzyme-kinetic information for investigating disease metabolism. In this work, a new exchange spectroscopic imaging method was applied to a preclinical cancer treatment study and the metabolic information provided by this new method agreed with and proved additional quantitative kinetic metrics over traditional Response Evaluation Criteria in Solid Tumors (RECIST) measures.
