- Tested in people
This was done in animals, not people. Most findings at this stage never become treatments.
This imaging method was only tested in rats.
The short version
Scientists tested a new ultrasound method that may show very small blood vessels, but so far only in rats.
What was studied. Researchers made a new way to process ultrasound images. It uses tiny gas bubbles in the blood to help see very small, slow-moving blood vessels.
What they found. The method picked up slow-moving bubbles that are usually hard to see. It showed small blood vessels in the brain, kidney, and testis of rats. It also showed blood vessels in an early-stage 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, a type of brain tumor.
What this means, and what it doesn't
What it could mean: Someday, a method like this might help doctors see the tiny blood vessels in and around a brain tumor more clearly. That could help them learn more about how a tumor grows.
What it doesn't mean: This does not mean the method is ready for people. It was only tested in rats. It is an imaging tool, not a treatment. It is not a cure. It would take many more years of testing before it could be part of everyday care.
