  1. 1. Blood flow assessment in cerebral arteries with 4D flow magnetic resonance imaging an automatic atlas-based approach

    University dissertation from Umeå : Umeå universitet

    Author : Tora Dunås; Umeå universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circle of Willis; 4D flow MRI; Cerebral arteries; Vascular disease; Stroke; Automatic labeling; Probabilistic atlas; Cerebral blood flow; Neuroimaging; Magnetic Resonance Imaging;

    Abstract : Background: Disturbed blood flow to the brain has been associated with several neurological diseases, from stroke and vascular diseases to Alzheimer’s and cognitive decline. To determine the cerebral arterial blood flow distribution, measurements are needed in both distal and proximal arteries. READ MORE

  2. 2. Cerebral blood flow distribution, collateral function and pulsatility in healthy and in patients with symptomatic carotid stenosis  a magnetic resonance imaging approach

    University dissertation from Umeå : Umeå universitet

    Author : Laleh Zarrinkoob; Umeå universitet.; Umeå universitet.; [2019]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aging; Arterial pulsatility; Carotid stenosis; Cerebral arteries; Cerebral blood flow; Cerebral collateral blood flow; Circle of Willis; Phase contrast magnetic resonance imaging;

    Abstract : Background: For the detection and treatment of early cerebral vascular disease it is of paramount importance to first understand the normal physiology of the cerebral vasculature, and subsequently, to understand how and when pathology can develop from that. This is especially important as the population above 65 years of age is increasing and aging itself is an established risk factor for the development of cerebral vascular disease. READ MORE

  3. 3. Cerebral blood flow and intracranial pulsatility studied with MRI measurement, physiological and pathophysiological aspects

    University dissertation from Umeå : Umeå universitet

    Author : Anders Wåhlin; Umeå universitet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Arterial Pulsatility; cerebrospinal fluid; cerebral blood flow; venous flow; intracranial pressure; pulse pressure; dementia; hippocampus; multiple sclerosis; magnetic resonance imaging; radiofysik; radiofysik;

    Abstract : During each cardiac cycle pulsatile arterial blood inflates the vascular bed of the brain, forcing cerebrospinal fluid (CSF) and venous blood out of the cranium. Excessive arterial pulsatility may be part of a harmful mechanism causing cognitive decline among elderly. READ MORE

  4. 4. Hypertension, blood pressure, cognition and cerebral blood flow in the cohort of "Men born 1914"

    University dissertation from Department of Health Sciences, Lund University

    Author : Faina Reinprecht; Lunds universitet.; Lund University.; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; samhällsmedicin; Social medicine; Socialmedicin; Gerontologi; Gerontology; neuropsykologi; neurofysiologi; neurophysiology; Neurologi; regional cerebral blood flow; cohort study; Neurology; neuropsychology; blood pressure; blood pressure monitoring; risk factors; Hypertension;

    Abstract : Popular Abstract in Swedish Flertal studier talar för att såväl vaskulär demens som demens av Alzheimers typ är relaterade till blodtrycksnivå tidigare under livet. En studie har visat att redan blodtrycket vid 50- årsåldern är relaterat till kognitiva (intellektuella) funktioner vid 70-års ålder. READ MORE

  5. 5. Cardiopulmonary Resuscitation Pharmacological Interventions for Augmentation of Cerebral Blood Flow

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jakob Johansson; Uppsala universitet.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; Adrenaline epinephrine ; Cardiac arrest; Cardiopulmonary resuscitation; Cerebral blood flow; Guidelines; Post-resuscitation period; Vasopressin; Anestesiologi och intensivvård; MEDICINE Surgery Anaesthetics and intensive care; MEDICIN Kirurgi Anestesiologi och intensivvård;

    Abstract : Cardiac arrest results in immediate interruption of blood flow. The primary goal of cardiopulmonary resuscitation (CPR) is to re-establish blood flow and hence oxygen delivery to the vital organs. READ MORE
