This looks across many earlier studies rather than running a new one.
This is a review of computer research, not a tool a doctor can use today.
The short version
Computer tools can spot brain tumors on scans, but they cannot help guide your care yet.
What was studied. Researchers pulled together 213 studies of computer tools that read brain MRI scans. The studies came out between 2018 and March 16, 2026.
What they found. Most studies taught computers to find, sort, or outline tumors on MRI scans. The tools scored high on the data used to test them. But only 18.8% were checked on scans from a new group of patients, and none tested how the tools held up when scans were taken in different ways.
What this means, and what it doesn't
What it could mean: Your scans are still read by a doctor, not by a computer. These tools may help doctors someday. For now, the proof that they work in real care is missing.
What it doesn't mean: This is not a new treatment, and it is not a cure. It is a review of computer research, not a study of patient care. The authors say the tools must first be tested on new groups of patients. Nothing here changes the care you get today.
