Hyperpolarized Imaging in Diagnosing Participants With Glioma
a study on Glioma
This 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.
Pilot Study of Safety and Feasibility of Acquiring Hyperpolarized Imaging in Patients With Gliomas
- To assess the safety and feasibility of hyperpolarized carbon C 13 (13C) magnetic resonance (MR) metabolic imaging as a new and unique tool for evaluating tumor burden and detecting early response to standard therapy in patients with glioma.
II. To define the most appropriate imaging parameters for obtaining hyperpolarized 13C data from the brain, sixty patients with evidence of residual disease from a prior MRI examination will be scanned with a slice select magnetic resonance spectroscopic (MRS) sequence, a dynamic 2dimensional (D) magnetic resonance spectroscopic imaging (MRSI) or a single time point 3D MRSI sequence after receiving an injection of hyperpolarized 13C pyruvate.
III. To establish the time course of changes in hyperpolarized pyruvate and lactate peaks on a voxel by voxel basis using dynamic 2D MRSI.
IV. To evaluate if patients who receive treatment with standard radiation and temozolomide exhibit a reduction in hyperpolarized 13C lactate/pyruvate at post-radiation follow-up compared to their baseline scan.
OUTLINE: Participants are assigned to 1 of 2 cohorts.
COHORT I: Patients receive hyperpolarized carbon C 13 pyruvate intravenously (IV) and undergo MRI.
COHORT II: Patients receive hyperpolarized carbon C 13 pyruvate IV and undergo MRI before standard treatment with radiation therapy and temozolomide and 4 weeks after completion of radiation therapy.
After completion of study treatment, participants are followed for up to 24 months.
