RATIONALE: Imaging procedures such as MRI may improve the ability to determine the response of brain tumors to therapy. PURPOSE: This clinical trial is studying how well MRI works in evaluating response to therapy in children with primary or metastatic brain tumors.

Study summary:

OBJECTIVES: - Define specific patterns of metabolites using long echo time multislice proton nuclear magnetic resonance spectroscopic imaging. - Attempt to distinguish spectroscopic patterns associated with tumor progression, tumor necrosis, radiation necrosis and tumor edema on conventional MRI imaging. - Determine if early metabolic changes are predictive of response in children with brain tumors treated with chemotherapy. OUTLINE: Patients undergo nuclear magnetic resonance spectroscopic (NMRS) imaging prior to therapy, immediately after the first cycle of therapy, and/or prior to subsequent cycles of therapy. After NMRS imaging, all patients are injected with IV gadolinium-DTPA and postcontrast T1-weighted images are performed. PROJECTED ACCRUAL: Approximately 50 patients will be accrued for this study.
