This was tested in people. That is the most reliable kind of research we share.
This was only tested on scans people had in the past, not used in real care yet.
The short version
Researchers tested computer software that draws around a pituitary tumor and nearby parts on a common MRI scan.
What was studied. Researchers looked back at MRI scans from 255 people who had surgery for a pituitary tumor. They tested two computer programs to see if the programs could outline the tumor, the pituitary gland, and the two large neck arteries that carry blood to the brain. Expert surgeons had already outlined these by hand, and that was used as the correct answer.
What they found. Both programs worked about the same. The outlines they drew matched the surgeons' outlines only fairly well, so the accuracy was modest. The programs did better at spotting which scan slices held the tumor and the arteries than at drawing exact borders. They were also weakest at outlining the pituitary gland itself. The software took 78.4 seconds per person on average.
What this means, and what it doesn't
What it could mean: Doctors already study MRI scans by hand before pituitary surgery. Software like this might one day help by giving a quick first draft of the outlines and a rough 3D picture. The researchers say it could be a helper tool, not a replacement for the doctor reading the scan.
What it doesn't mean: This does not mean the software is ready for your care. It was tested on scans that were already taken, not on people going into surgery today. The programs were not accurate enough on their own, and the authors call this a first feasibility test. It is not a treatment, and it is not a cure or a promise of one. It does not change how pituitary tumors are removed or treated.
