Brief Summary

The recent development of dissolution dynamic nuclear polarization (DNP) technology for hyperpolarized (HP) 13C imaging offers a promising new avenue for non-invasively accessing fundamental metabolic...

Detailed Description

PRIMARY OBJECTIVES: 1. Optimize scan parameters in order to maximize the signal-to-noise ratio of the HP 13C-pyruvate magnetic resonance imaging (MRI) in the liver. 2. Determine whether the level of ...
