RecruitingPhase 1Radiation therapyHyperpolarized Imaging in Diagnosing Participants With GliomaThis pilot trial studies the side effects of hyperpolarized carbon C 13 pyruvate magnetic resonance imaging (MRI) in diagnosing participants with glioma. Diagnostic procedures, such as hyperpolarized carbon C 13 pyruvate MRI, may help find and diagnose glioma.
