Hyperpolarized Pyruvate Injection in Subjects With Prostate Cancer

Summary

Current imaging options do not assess prostate cancer well. This study will combine two magnetic resonance imaging modalities, MRI and MRSI, in order to determine the utility to physicians and patients with prostate cancer in making treatment decisions and seeing how well various types of treatment work. Hyperpolarized pyruvate (13C) is an investigational product that may enhance the imaging capability of MRI and MRSI. Hyperpolarized pyruvate will be injected into the body to determine how it is metabolized and how it's metabolism can be assessed using MR imaging. The purpose of this study is to determine the safety and metabolism of hyperpolarized pyruvate in humans, and how this can be used to increase the effectiveness of MR imaging with regards to patient care.
