How far along is this research?
This is a trial that is enrolling or has been updated. It is not a finding yet.
This is a mid-stage study that is still testing how well the scan works.
Status: Recruiting. It is looking for patients now. Talk to your care team about whether it fits you.

The short version
This study is testing whether a scan can show how much oxygen gets into a brain tumor.
Who this trial is for. This study is for people with cancerous brain tumors. It tests a tracer called FMISO. The tracer is used with a PET/MRI scan to show oxygen levels in the tumor.
Where it stands. The study is checking how well FMISO scans show oxygen in brain tumors. Oxygen levels may affect how a tumor behaves. The trial has not reported results yet.
What this means, and what it doesn't
What it could mean: A scan like this may one day help doctors learn more about a tumor. If you have a cancerous brain tumor, you can ask your care team if this study might fit you.
What it doesn't mean: This is a test, not a proven tool or treatment. The scan does not treat the tumor. Joining a trial does not promise any benefit. It is not a cure.
