This looks across many earlier studies rather than running a new one.
This is a review of where the science stands, not a new result.
The short version
A special kind of MRI can show what a brain tumor is made of, with no surgery.
What was studied. This is a review paper about a special MRI scan that reads brain tumor chemistry. It covers what doctors use now and what is still being worked on.
What they found. Tumors show a set chemical pattern on these scans. One chemical goes up and another goes down. This can help doctors grade a glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary, and tell new tumor growth apart from changes caused by treatment. The scans can also map where a tumor is most active, which may help plan a biopsy, surgery, or radiation.
What this means, and what it doesn't
What it could mean: If your hospital offers this scan, it may add useful detail about your tumor. That detail could help your team plan tests or treatment without more surgery.
What it doesn't mean: This is a summary of past work, not a new study and not a new treatment. The scan does not treat a tumor, and it is not a cure. Many centers do not do the scan the same way, and some do not offer it at all. The newer versions of it are still research only.
