How far along is this research?
This is a trial that is enrolling or has been updated. It is not a finding yet.
No phase was given for this study, so we treat it as an early test in people.
Status: Not yet recruiting. It has not opened yet. Ask your care team to watch for it if it looks like a fit.

The short version
This trial is testing whether a special brain scan can tell growing tumor apart from damage left by radiation.
Who this trial is for. This trial is for people who have brain metastases, which are tumors that spread to the brain from somewhere else in the body. It is testing how well an amino acid PET scan can tell radiation damage apart from tumor that is growing.
Where it stands. The trial has not reported results. It is looking at how well this scan tells the two things apart. That answer is not in yet.
What this means, and what it doesn't
What it could mean: Telling radiation damage from growing tumor can change what care a person is offered, and it can change what doctors expect. This scan is being tested to see if it helps with that. If this sounds like your situation, you could ask your care team about it.
What it doesn't mean: This does not mean the scan is proven. A trial is a test, not care your own doctor can give you yet. Being in a trial does not promise that it will help you. And this is not a cure.
