RecruitingProcedureMagnetic Resonance (MR) Imaging to Determine High Risk Areas in Patients With Malignant Gliomas and to Design Potential Radiation Plans and to Examine Metabolite Changes in Gliomas and Other Solid TumorsThe researchers think that the use of advanced MR imaging may help people with this disease, because it may better predict areas within a malignant glioma (brain tumor) that are at a high risk of recurring. WeThe reserchers are doing this study to see whether this advanced imaging is a safe treatment that causes few or mild side effects in people with brain tumors.
