This study looks at using a special type of MRI called spectroscopic MRI to help guide proton therapy in kids with brain tumors. MRI stands for magnetic resonance imaging, which is a way to take pictures of the inside of your body without using X-rays. This study does not involve any injections or dyes. Researchers want to see if this imaging can help identify changes in tumor metabolism, which is how the tumor uses energy, compared to healthy tissue.

• This study includes multiple MRI scans before and after proton therapy, up to 7 months.
• Participants must have a high-grade glioma, a specific type of brain tumor.
• This is a long-term study that tracks health and quality of life over time.

To join, you need to be able to have an MRI, which means you can't have certain metal implants like pacemakers or cochlear implants. The study is open to all genders and races, ensuring a wide range of participants. Overall, this study aims to improve how proton therapy is given and track how well it works in treating brain tumors.
