- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This scan was only looked at in a few patients, and it has not been proven to help yet.
The short version
Doctors looked at a special kind of MRI scan in four people after brain surgery for cancer that had spread to the brain.
What was studied. This study looked back at four patients who had surgery to remove cancer that spread to the brain. After surgery, they had a special MRI scan that shows how a dye moves in and out of the area over time.
What they found. The scans showed four different patterns in the space left after surgery. In patients whose scans did not show certain warning signs, the cancer did not come back in that spot, and they skipped extra radiation and kept getting checkups. In one patient, the scan showed small warning areas, and the cancer later came back in those same areas.
What this means, and what it doesn't
What it could mean: Someday, this kind of scan might help doctors tell healing tissue apart from cancer that is coming back. That could help them decide who needs more radiation after surgery.
What it doesn't mean: This was a very small study of only four people, picked to show examples. It does not prove the scan works, and it is not part of everyday care yet. More studies are needed. This is not a cure and does not treat the cancer.
