ARTERIAL STIFFNESS AND CEREBRAL BLOOD FLOW AMONG OLDER ADULTS
… for the vascular factors arterial stiffness and cerebral blood flow (CBF) with mild cognitive impairment (MCI). This study analyzes arterial stiffness and CBF as potential pre-clinical factors of AD in the Alzheimer’s Disease Prevention Participant Repository (ADPPR) cohort. There was a total of …

Optical Cerebral Blood Flow Monitoring of Mice to Men
This thesis describes cerebral hemodynamic monitoring with the optical techniques of diffuse optical spectroscopy (DOS) and diffuse correlation spectroscopy (DCS). DOS and DCS both employ near-infrared light to investigate tissue physiology millimeters to centimeters below the tissue surface. DOS …

Mapping cerebral blood flow with speckle contrast optical spectroscopy
Cerebral blood flow (CBF) is a critical component of cerebral hemodynamics, yet the existing optical neuroimaging modalities to measure CBF do not have sufficient signal-to-noise ratio. Speckle contrast optical spectroscopy (SCOS) has been previously considered as an alternative approach to use …

Measurement of Cerebral Blood Flow Using Arterial Spin Labeling Magnetic Resonance Imaging
Cerebral Blood Flow (CBF) reflects the amount of blood perfusion in the brain, often defined as ml of blood per 100 gram of brain per minute. CBF is an important measure in understanding brain physiology and pathophysiology. Thus, it is important to establish a robust method suitable for …

The Baroreflex And Neurogenic Control Of Cerebral Autoregulation In Cerebral Blood Flow
Introduction The neurogenic component of cerebral autoregulation (CA) refers to those mechanisms controlling cerebral blood flow under the influence of the nervous system, and which rely on the innervation of the cerebral blood vessels. The neurogenic control of CA is incompletely understood. …

Patterns of Fetal Lamb Regional Cerebral Blood Flow during and after Prolonged Hypoxia
… intrauterine hypoxia, total and regional cerebral blood flows increase to the same extent without evidence of preferential shunting to critical brainstem or subcortical areas. Neuropathologic studies have indicated relative sparing of these areas during similar animal experimental or human …

Normalization of Cerebral Blood Flow, Neurochemicals, and White Matter Integrity After Kidney Transplantation
… (CKD) is associated with abnormalities in cerebral blood flow (CBF), cerebral neurochemical concentrations and white matter integrity, each of which are associated with adverse clinical consequences in the non-CKD population, and may explain the high prevalence of dementia and stroke in end …

Effects of Cerebral Blood Flow and Temperature on Executive Function During Moderate Hyperthermia
… heat stress may be affected by changes in cerebral blood flow (CBF) as opposed to thermal perception changes. An end-tidal forcing system was used to maintain eucapnia and baseline CBF in the isocapnic trial during the hypocapnia-induced CBF reduction. Repeated measures analysis of variance …

3D reconstruction of cerebral blood flow and vessel morphology from x-ray rotational angiography
Three-dimensional (3D) information on blood flow and vessel morphology is important when assessing cerebrovascular disease and when monitoring interventions. Rotational angiography is nowadays routinely used to determine the geometry of the cerebral vasculature. To this end, contrast agent is …

Sex-specific differences in the association between history of concussion and cerebral blood flow volume
… measurement of cervical arteries contributing to cerebral blood flow (Common Carotid Artery; CCA, Internal Carotid Artery; ICA and Vertebral artery; VA) between male and female athletes with and without a history of concussion (HOC). One hundred and two (102) asymptomatic university athletes were …

Cerebral blood flow in the non-human primate : an in vivo model and drug interventions
Cerebral blood flow dynamics is an essential component for preserving cerebral integrity. Cerebral blood flow abnormalities are often seen in patients with central nervous system pathologies such as epilepsy, migraine, Alzheimer's Disease, vascular dementia, stroke, and even HIV/AIDS. There is …

Hypertension, blood pressure, cognition and cerebral blood flow in the cohort of "Men born 1914"
… of carotid arteries, 24-hour ambulatory blood pressure monitoring, regional cerebral blood flow, and cardiovascular risk factors. It is well known that hypertension plays a major etiological role in the development of cerebrovascular disease, ischemic heart disease, and cardiac failure. …

Transcranial Doppler sonography: a new noninvasive method for measuring toxicant-induced alterations in cerebral blood flow
… in the dog to noninvasively measure changes in cerebral blood flow (CBF) resulting from a low-level exposure to the commonly used pyrethroid insecticide deltamethrin. Deltamethrin has previously been shown to increase CBF in rats as determined by other techniques. In this experiment, …

<sup>133</sup>Xe Inhalation Technique: Effect of the Contralateral Contribution on Regional Cerebral Blood Flow Parameters.
The method of estimating regional cerebral blood flow (rCBF), which involves inhalation of the gaseous radioisotope 133Xe, was introduced by Mallett and Veall, and later modified by Obrist, et al. The details of our laboratory arrangement at University Hospital have been previously reported. The …

Neuropsychological Functioning and Regional Cerebral Blood Flow: A Comparison Between Aged Normals and Alzheimer’s Type Dementia.
… Xenon inhalation method of determining regional cerebral blood flow (rCBF). In addition, correlations between rCBF detectors and Luria-Nebraska localization scales were investigated in order to ascertain possible agreement on focal areas of functional brain tissue loss. Nine subjects with …

Regional Low Cerebral Blood Flow Predicts Leukoaraiosis Development at 18 Months in Patients with TIA and Minor Stroke
… of this study was to investigate whether low cerebral blood flow (CBF) is associated with subsequent white matter hyperintensity (WMH) development in minor stroke and transient ischemic attack (TIA) patients. New WMH at 18 months were identified by comparing follow-up with baseline FLAIR, and …
