Clinical Trial Summary

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.


Clinical Trial Description

PRIMARY OBJECTIVES: I. To assess the safety of intravenous (IV) injection of hyperpolarized carbon C 13 pyruvate (hyperpolarized [1-13C] pyruvate) for magnetic resonance imaging (MRI). II. To assess the frequency and sensitivity with which lactate and bicarbonate signals can be detected in malignant brain tumors after IV injection of hyperpolarized [1-13C] pyruvate. OUTLINE: Participants undergo MRI over 45 minutes at baseline. Participants then receive hyperpolarized carbon C 13 pyruvate IV over 30-40 seconds. Within 1 minute, participants undergo magnetic resonance spectroscopic imaging (MRSI) over 3 minutes and MRI over 10 minutes (participants may receive gadolinium at the discretion of the protocol director). After completion of study, participants are followed up periodically. ;
