- Tested in people
This was done in animals, not people. Most findings at this stage never become treatments.
This was an early computer study of scans, mostly from dogs, and is not ready for patients.
The short version
Researchers found that brain tumors in dogs and people can look alike on MRI scans.
What was studied. Researchers looked at MRI brain scans from dogs with gliomas and people with glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary. They used computer tools to measure the texture, shape, and brightness of the tumors and of healthy brain tissue.
What they found. Some scan patterns could tell tumor tissue apart from healthy tissue, in both dogs and people. A computer program sorted tumor from healthy tissue with 80.33% accuracy. The tumor patterns in dogs and people looked much alike.
What this means, and what it doesn't
What it could mean: Dogs that get these tumors on their own may help scientists study the human disease. Someday, scan patterns like these might help doctors find and track brain tumors without surgery.
What it doesn't mean: This is early research. It does not change how brain tumors are found or treated today. The authors say the study was small and needs to be checked in larger groups. It is not a new treatment, and it is not a cure.
