To simulate blood flow inside brain aneurysms, researchers from Japan have developed a computational method that combines 4D ...

During vascular occlusions, the blood flow distribution in the cerebroarterial tree changes and can lead to insufficient blood flow, which can in turn cause tissue damage or ischemia. In such ...

Background: In older age, the benefits of antihypertensive treatment (AHT) become less evident, with greater associated risk. Of particular concern is compromising cerebral blood flow (CBF), ...

Cerebral autoregulation is a homeostatic mechanism which maintains blood flow despite changes in blood pressure in order to meet local metabolic demands. Several mechanisms play a role in cerebral ...

eLife assessment This manuscript provides a useful characterization of penumbral microvascular flow disturbances over the first hours after ischemia onset in a rat model of middle cerebral artery ...

Cerebral hemodynamics play an important role in the development of cerebrovascular diseases. In this work, we propose a numerical framework for modeling patient-specific cerebral blood flow, using ...

AIM To determine if the haemodynamics of systemic and cerebral circulation are changed during treatment for persistent pulmonary hypertension of the newborn (PPHN). METHODS Fifteen term newborn ...

With ASL, arterial blood is magnetically labeled and used as endogenous tracer flowing into the tissue of interest, which is most often the brain. The distribution of the label over the different ...

Real-time digital subtraction angiography (DSA) is capable of revealing the cerebral vascular morphology and blood flow perfusion patterns of arterial venous malformations (AVMs). In this study, we ...

Cerebral blood flow helps to maintains brain function, and a prolonged insufficiency causes degeneration and irreversible impairment.

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 ...

Cerebral blood flow (CBF) of key regions of newborns' brains is altered in very premature infants and may provide an early warning sign of disturbed brain maturation well before such injury is ...
