The circle of Willis is an anastomotic network of arteries surrounding the base of the brain,
providing collateral circulation to prevent ischemia. It has, however, long been established …

MRI is invaluable in assessing the neonatal brain following suspected perinatal injury. Good
quality imaging requires adaptations to both the hardware and the sequences used for …

Abstract The circle of Willis (CoW) is an anastomotic arterial network located on the base of
the brain. Studies have shown that it demonstrates considerable anatomical variation in …

Background Preterm infants follow an altered neurodevelopmental trajectory compared to
their term born peers as a result of the influence of early birth, and the altered environment …

Objective The circle of Willis (CoW) is the foremost anastomosis and blood distribution
center of the brain. Its effectiveness depends on its completion and the size and patency of …

We describe a patient-specific simulation based investigation on the role of Circle of Willis
anatomy in cardioembolic stroke. Our simulation framework consists of medical image …

Background Carotid artery access in infants with congenital heart disease undergoing
cardiac catheterization via a surgical cut down has been well described. There is a paucity …

Variation in blood flow mediated by the posterior communicating collateral arteries (PComs)
contributes to variation in the severity of tissue injury in obstructive disease. Evidence in …

Aim Neonatal arterial ischemic stroke (NAIS) results from a focal disruption of the blood flow
in a cerebral artery by a not well understood mechanism. Our objective is to describe the …

Background: Anatomic variants of the circle of Willis (CW) are commonly observed in healthy
subjects. Genetic and environmental factors influencing these variants remain unclear. Our …
