Hyperpolarized Carbon C 13 Pyruvate Magnetic Resonance Spectroscopic Imaging in Detecting Lactate and Bicarbonate in Participants With Central Nervous System Tumors

Not Recruiting

Trial ID: NCT03565367


This early phase I trial studies how well hyperpolarized carbon C 13 pyruvate magnetic resonance imaging works in detecting lactate and bicarbonate in participants with central nervous system tumors. Hyperpolarized carbon C 13 pyruvate magnetic resonance imaging may be used to measure the metabolic state of malignant brain tumors.

Official Title

A Pilot Study to Assess Lactate and Bicarbonate Detection Within Malignant Brain Tumors Using [1-13C]-Pyruvate DNP Magnetic Resonance Spectroscopy (MRS)
