In order to function properly, the brain requires a steady flow of blood through the cerebral arteries and veins, which deliver oxygen and nutrients and also remove metabolic byproducts. Therefore, ...

Measuring blood flow in the brain is critical for understanding response to a range of neurological problems, including stroke, traumatic brain injury (TBI) and vascular dementia. Obtaining such ...

Arterial spin labeling (ASL) is a non‐invasive magnetic resonance imaging technique that exploits magnetically labelled arterial blood water as an endogenous tracer to quantitatively assess cerebral ...

With $5.1 million in funding, the STAT earpiece measures blood flow to head 24/7 to better understand symptoms that occur upon standing, such as dizziness, brain fog, headaches, fainting, and fatigue ...

A novel, minimally invasive method of determining whether fatty deposits in a coronary artery are restricting blood flow to a patient's heart performed similarly to the standard, more-invasive ...

Scientists develop an optical technique that can image dynamic changes in the cerebral blood flow to diagnose brain health. Cerebral blood flow (CBF), which supplies oxygen and nutrients to our brain, ...

If CBF ceases to function properly, cognitive functions decline. “Cerebral blood flow (CBF) is an important factor that maintains brain function, and a prolonged insufficiency causes degeneration and ...

Diffuse correlation spectroscopy (DCS) is used for noninvasive detection of blood flow. However, current DCS devices need to be improved to increase the signal-to-noise ratio for more accurate ...
