This was tested in people. That is the most reliable kind of research we share.
It was tested in healthy people and in two patients, as a first look only.
The short version
Researchers built a computer tool that gets brain scan results in five minutes instead of many.
What was studied. Researchers scanned 18 healthy people with a 50 minute brain scan. They then trained a computer tool to get the same results from only a five minute part of that scan.
What they found. The computer tool matched the long scan better than the older math method did. Its errors were up to two-fold lower. For one whole brain scan, the tool gave answers in a few seconds instead of more than an hour. It still worked well on a sharper scan with 1.7 mm detail. The team also tried it on two people with a brain tumor called glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary.
What this means, and what it doesn't
What it could mean: Someday this kind of brain scan may take about five minutes. Short scans are easier when you feel sick or cannot lie still. Faster results could also make it easier for doctors to study this scan.
What it doesn't mean: This is not a treatment, and it is not a cure. It is an early test of a way to take and read a scan. Only two people with a brain tumor were scanned, and that was just a first look. Nothing here shows that people live longer or feel better. This is not part of normal care today.
