▪ Abstract The characterization of blood flow is important for understanding the function of
the cardiovascular system under normal and diseased conditions, designing cardiovascular …

PURPOSE: To prospectively determine the effect of anatomic variations in the circle of Willis
on volume flow in the internal carotid arteries (ICAs) and basilar artery (BA). MATERIALS …

BACKGROUND AND PURPOSE: Optimal estimation of cerebral blood-flow volume (BFV)
may be an important indicator for better evaluation of the patients with cerebrovascular …

Phase-contrast magnetic resonance imaging (PC-MRI) or flow-sensitive MRI can be used to
noninvasively measure intracranial vascular and CSF flow. Monro-Kellie homeostasis is the …

Study objective: To examine the effect of dexmedetomidine on CBF in critical ill patients with
or without TBI. Research design: Prospective controlled trial (ISRCTN57998533). Methods …

Phase contrast magnetic resonance imaging (PC-MRI) and color-coded duplex
ultrasonography (CDUS) are commonly used for measuring cerebral blood flow in the …

Objective The objective of the study was to investigate the cerebrovascular hemodynamic
response of cervical spine positions including rotation and cervical spine manipulation in …

The aim of the present study was to investigate the course of cerebral blood flow (CBF) and
metabolism in traumatic brain injury (TBI) patients and to specifically characterize the …

Objective It is hypothesised that cervical manipulation may increase the risk of
cerebrovascular accidents. We aimed to determine whether cervical spine manipulation is …

Objective. Volumetric flow measurement with Doppler ultrasound is useful in assessing
blood flow as part of an evaluation of arteriovenous fistula maturity in patients undergoing …
