This phase 1 study tests a new PET imaging tracer called 89Zr-cRGDY in 17 people with malignant brain tumors or pituitary adenomas. The tracer is given in a very small dose to see how it spreads and clears from the body. The goal is to improve brain tumor imaging, not to treat th…

This study uses a special PET scan to measure brain inflammation in children with medulloblastoma who receive whole-brain radiation. Twenty-two participants will be scanned four times over two years to see how inflammation changes. The goal is to understand how radiation affects …

This study looks at two types of radiation for people with 5 to 30 brain tumors that have spread from other cancers. One group gets focused radiation (SRS) alone, the other gets whole-brain radiation plus SRS. The main goal is to see which approach better protects memory and thin…

This study looks at how seizures change over time in people with low grade glioma (a slow-growing brain tumor) who are on treatment. By tracking seizure frequency and comparing it to MRI scans, researchers hope to find early signs of tumor changes. The goal is to help doctors det…
