A scan called 18F-FET PET tested for finding glioma before surgery
Original title: Clinical Benefit of 18F-FET in Glioma.
How far along is this research?
This is a trial that is enrolling or has been updated. It is not a finding yet.
This is a late stage trial in people, but it is still a test and not regular care.
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 study tests whether a special brain scan can show 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 more clearly than an MRI does.
Who this trial is for. This trial is for people with a suspected primary 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 who are already scheduled for brain surgery, and it also includes healthy volunteers. It tests a scan called 18F-FET PET/CT and compares what it shows with a regular brain MRI, then checks both against the tissue taken during surgery.
Where it stands. There are no results yet. The trial plans to enroll 36 participants, made up of 6 healthy volunteers and 30 patients. It is measuring how well the scan finds 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 compared with MRI, and it is also tracking side effects and vital signs. The trial has not reported results.
What this means, and what it doesn't
What it could mean: If this scan works well, doctors may one day get a clearer picture of a brain tumor before surgery. That is not settled yet. It is a study, and it is happening at one center in Taiwan. Someone who fits the study could ask their care team about it.
What it doesn't mean: This does not mean the scan is proven. A trial is a test, not a treatment you can count on. Joining a study is not a guarantee that it will help you. This is not a cure, and it is not a promise of one. It also does not mean this scan will replace an MRI.
