This study aims to explore a new type of magnetic resonance imaging (MRI) called Chemical Exchange Saturation Transfer (CEST) in children aged 6-18 years with brain tumors. An MRI is a machine that takes detailed pictures of the brain. The CEST MRI used in this study is still being tested and has not been approved by the FDA yet. The study wants to find out if this new type of MRI can help doctors evaluate brain tumors. CEST MRI creates images using water molecules and protons in the brain. Early research shows that CEST could be helpful in understanding brain tumor changes.

This study will enroll 5 participants.

The Synovial Sarcoma Registry and Biospecimen Repository was opened in June of 2023 with the goal of furthering research and improving outcomes for patients with synovial sarcoma. This study is open to anyone treated in the United States. You do NOT have to travel to Philadelphia to participate.
