This looks across many earlier studies rather than running a new one.
It pulled together a few past studies of patients, and this scan is not standard care.
The short version
A special MRI scan may help show if a brain tumor is growing again, but it is not proven yet.
What was studied. Researchers gathered seven studies of people with glioma: A tumor that starts in the glial cells. Those are the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4. The grade says how the tumor is expected to act. See the glossary after treatment. The studies used a special MRI scan called APT, and five of them covered 218 patients.
What they found. All five of those studies found a stronger scan signal when the tumor was growing than when the change came from treatment. The studies did not agree well with each other, so the size of that difference is still unclear. Some studies checked the cause with a tissue test, while three used only later scans.
What this means, and what it doesn't
What it could mean: After treatment, brain scans can be hard to read. This kind of MRI may one day give doctors one more clue to work with. For now it is a research tool, so ask your care team what scans they use.
What it doesn't mean: This does not mean the scan can tell you what is going on in your own brain. It was a review of a few small studies that did not agree, so the result is not firm. The authors say it needs to be tested again in better planned studies. This is not a treatment, and it is not a cure.
