This looks across many earlier studies rather than running a new one.
This was a review of early studies, not a new result.
The short version
Doctors are testing a new dye for brain scans, but it is still early.
What was studied. Researchers gathered past studies of a new PET scan dye called CXCR4. The dye is made to stick to a marker found on some tumor cells. They looked at studies that used it in people with glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary, a type of brain tumor.
What they found. The dye barely shows up in healthy brain tissue. That helps tumors stand out clearly on the scan. It tended to show up more in higher grade gliomas. But the scan results did not always match lab tests of the tumor.
What this means, and what it doesn't
What it could mean: This scan may one day give doctors extra information about a glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary. Early studies looked at telling tumor regrowth apart from changes caused by treatment. Some also looked at planning radiation. It is not part of normal care today.
What it doesn't mean: This is not a treatment, and it is not a cure. It is a review of early, small studies, not a new test result. The studies were few and did not all agree. Bigger studies at many hospitals are needed first. Your doctor cannot order this scan as routine care.
