Patients with heart disease could benefit from less extensive interventions thanks to cutting-edge technology that creates 3D computer models of blood flow through the heart's arteries, according to ...

Researchers developed a wearable device that can be used for non-invasive stroke risk assessment. The device uses speckle contrast optical spectroscopy to track changes in blood flow and volume in the ...

For more than a century, scientists have known that blood vessels can rhythmically contract and relax in a process called vasomotion. In the brain, these subtle oscillations are thought to help ...

Researchers at NYU Langone Health discovered that cutting off blood flow accelerates cancer growth by prematurely aging the ...

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 ...

A sudden restriction of blood flow to the brain. That's how scientists have traditionally explained why people faint. But several mysteries remain: What causes someone's blood flow to spontaneously ...
