This was tested in people. That is the most reliable kind of research we share.
It was used in real patients, but it is not yet proven better than regular scans.
The short version
Doctors joined several scans into one detailed picture to help plan surgery for a type of brain tumor.
What was studied. Doctors looked back at the records of 72 people with meningiomas, a type of brain tumor. Before surgery, each person's MRI, CT, and blood vessel scans were joined into one detailed model.
What they found. The scans found unusual blood vessels in 10 patients, including 9 aneurysms. An aneurysm is a weak, bulging spot in a blood vessel. Doctors removed all or nearly all of the tumor in 67 patients (93.1%). Problems around the time of surgery happened in 5 patients (6.9%), and none came from the blood vessel scan.
What this means, and what it doesn't
What it could mean: For some hard-to-reach tumors, this kind of model may help surgeons plan. It may help most when a tumor sits at the base of the skull or near large blood vessels or veins.
What it doesn't mean: This study only looked back at past cases, and there was no comparison group. It does not show this method is better than regular scans. It does not mean every person with a meningioma needs it. It is a planning tool, not a treatment, and not a cure. More careful studies are needed before it could become routine care.
