Purpose: This study checks if a special PET scan using 68Ga-PSMA-11 helps see tumors in people with brain cancer. The PET/CT scan is a type of imaging that shows activity in the brain's cancerous areas.
Eligibility: You can join if you are 18 or older, understand and agree to the study, and have been treated for high-grade glioma (HGG) or brain metastases. You should also be planning to have a biopsy (a test where a small piece of tissue is taken) or surgery on the brain tumor. You cannot join if you are pregnant, have certain health issues, or if you are unable to undergo the PET scan.
- This study is for adults who have had previous treatment for brain cancer.
- Participants need to get a special PET/CT scan.
- Pregnant women or those with certain health issues cannot participate.
