Malignant Central Nervous System Neoplasm, Metastatic Malignant Neoplasm in the Central Nervous System
Conditions
Brief 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.
Detailed 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.
