This was tested in people. That is the most reliable kind of research we share.
This tool was only tested on past records from people, not in real care yet.
The short version
Scientists built a computer tool to tell two look alike brain lumps apart.
What was studied. Researchers used MRI scans, blood tests, and records from 188 people. Of those, 122 had brain lumps caused by TB (tuberculosis) and 66 had lung cancer that spread to the brain. They then tested the tool on 51 more people from another hospital, 26 with TB lumps and 25 with spread cancer.
What they found. The tool used only four things: the person's age, a blood test called CEA, having more than one lump, and a ring shape with a small bump on it. One computer method worked best. On the 51 people from the other hospital, it got 88.0% of one group right and 92.3% of the other group right.
What this means, and what it doesn't
What it could mean: These two problems can look almost the same on an MRI. But they need very different care. A tool like this might help doctors tell them apart sooner, without surgery to take a sample.
What it doesn't mean: This is not a treatment, and it is not a cure. It is an early tool, not something a patient can ask for today. It was built and checked using old records, not in daily clinic use. Doctors still rely on scans, blood tests, and sometimes a tissue sample. It would need testing in more hospitals and more people first.
