Study Summary

This is a single center prospective imaging study investigating the utility of hyperpolarized 13C-pyruvate +/-13C,15N-Urea/ metabolic MR imaging. The current protocol will serve as a companion imaging biomarker study paired with standard of care (SOC) therapeutics, as well as investigational therapies that participants may be scheduled to receive outside of this protocol.

Primary Outcome

Signal-to-noise ratios is defined as a MR/spectroscopy parameter, consisting of the HP C13-Pyruvate or Lactate signal (peak) relative to background noise level (baseline) in MRI spectra of the tissue. For the analysis and interpretation of the HP 13C-pyruvate MR imaging data, DICOM software package (SIVIC) will be used to align, display and quantitatively interrogate serial multi-parametric imaging data.
