Description
Bruno de Almeida and co-authors published a research paper in 2025 on imaging the pulses that move fluid through the brain. That flow washes out waste such as amyloid and tau, and it may falter in Alzheimer's disease. Using a very strong scanner and very fast imaging, the team built a way to watch the pulses as they happen.
Six volunteers were scanned with a custom coil setup built in-house. Whole-brain coverage was gathered in slabs for most of them. Math tools then split the signal by rhythm to map pulse strength in grey matter, white matter, and fluid spaces. A clear map of healthy pulses gives doctors a baseline for spotting flow trouble in patients.
