Content

Hyperpolarization is a novel technique to enhance NMR signal of 13C labeled molecules > 10,000 times, which can visualize dynamic metabolic reactions in the body. Simultaneous imaging of exogenously administered multiple metabolic probes will make it possible to non-invasively detect the homeostasis disruption resulting from various diseases.
