Researchers at the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have developed a brain imaging technique that reveals how tiny blood vessels in the brain pulse with each heartbeat—changes that may hold clues to aging and diseases such as Alzheimer’s.
The study, published in Nature Cardiovascular Research, introduces the first noninvasive method for measuring “microvascular volumetric pulsatility”—the rhythmic expansion and contraction of the brain’s smallest vessels—in living humans.
Using ultra-high-f...
