Cerebrovascular diseases such as atherosclerosis and stroke remain a major cause of morbidity and mortality worldwide. A common feature of these diseases is vascular stenosis, i.e., the narrowing of ...

Blood flow restriction training—once a niche rehabilitation method used primarily by physical therapists—has quietly transformed into one of fitness’s most intriguing innovations. This technique uses ...

To simulate blood flow inside brain aneurysms, researchers from Japan have developed a computational method that combines 4D flow MRI, computational fluid dynamics, and data assimilation, which ...

Caltech and the Keck School of Medicine of USC have developed a new laser-based headset device that can noninvasively measure blood flow and volume. Caltech postdoctoral scholar Simon Mahler is shown ...

Setup of the laser speckle contrast optical spectroscopy system used to monitor scalp and brain blood flow during temporary blockage of a major scalp artery near the temple. WASHINGTON, Oct. 21, 2025 ...

A new study suggests that dementia may be driven in part by faulty blood flow in the brain. Researchers found that losing a key lipid causes blood vessels to become overactive, disrupting circulation ...

Risk assessment Researchers from Caltech and the Keck School of Medicine at USC have created a portable laser-based headset that can estimate stroke risk. Caltech postdoctoral scholar Simon Mahler is ...

The co-founder and CEO of Total Flow Medical Ltd, Hilary Pierce, reported the filing of a patent for bidirectional flow cannulas configured and designed to replace conventional femoral arterial ...

Researchers have developed a laser-based device that can measure blood flow noninvasively and differentiate stroke risk based on current physiological conditions. When physicians want to know more ...
