This was tested in people. That is the most reliable kind of research we share.
This was tested on scans from patients, but it is a research method and not part of regular care.
The short version
Researchers tested an MRI method that removes the blur from water in the brain, so dense tumor areas show up better.
What was studied. Researchers tested a new way to measure how water moves inside brain tissue on MRI. They used computer simulations and 3 T MRI scans from 60 patients. Of those patients, 55 had adult-type diffuse gliomas and 5 had brain metastases.
What they found. The new maps showed areas of reduced diffusion better than the standard maps. Free water, from spinal fluid or swelling, can hide these areas on the usual scans. Areas that stood out on the new maps were seen more often in glioblastomas than in the other type of 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.
What this means, and what it doesn't
What it could mean: If this holds up, MRI scans may one day show the busiest, most packed parts of a tumor more clearly. That could help doctors see the tumor better and get a hint about what type it is. For now, it is a research method being studied.
What it doesn't mean: This is not a treatment. It does not shrink a tumor or help you live longer. It is an imaging method tested on scans from a small group of patients, and it is early. It is not something you can ask for at a normal scan appointment yet. It is not a cure or a promise of one.
