  1. 21. Ultrasound evaluation of atherosclerosis and other cardiovascular sources of cerebral embolism

    Författare :Robert Wetterholm; Göteborgs universitet; []
    Nyckelord :stroke; atherosclerosis; aorta; echocardiography; ultrasound; IMT; MES; WHHL;

    Sammanfattning : The search for embolic sources has high priority in patients presenting with suspected cerebral embolism. Non-invasive cardiovascular ultrasound is frequently used to reveal the presence of carotid stenosis and cardiac disorders with embolic potential. LÄS MER

  2. 22. 4D flow MRI and modelling to assess cerebral arterial hemodynamics : method development and evaluation, with implementation in patients with symptomatic carotid stenosis

    Författare :Madelene Holmgren; Anders Eklund; Jan Malm; Anders Wåhlin; Sara Qvarlander; Ronnie Wirestam; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 4D flow MRI; carotid stenosis; cerebral blood flow; cerebral arterial compliance; cerebrovascular resistance; circleof Willis; computational fluid dynamics; magnetic resonance imaging; stroke; vascular disease; Neurology; neurologi;

    Sammanfattning : Blood flow measurements are important for understanding the development of cerebrovascular diseases. With 4D flow magnetic resonance imaging (4D flow MRI), simultaneous velocity measurements are obtained in all cerebral arteries in a scan of about ten minutes. However, 4D flow MRI is a relatively new technique. LÄS MER

  3. 23. Hereditary risk factors for stroke in humans - Association studies with emphasis on familial and genotypic factors

    Författare :Håkan Lövkvist; Lund Neurologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allelic association; candidate genes; case-control; family history; ischemic stroke; polymorphisms.;

    Sammanfattning : Background Stroke is a serious vascular disorder that comprises intracerebral hemorrhages, subarachnoid hemorrhages and ischemic stroke (IS). The etiology of stroke, including hereditary components induced by cellular mechanisms, is therefore a research field of vital importance. LÄS MER

  4. 24. Detection of paroxysmal atrial fibrillation : with special emphasis on intermittent ECG recording

    Författare :Peter Doliwa; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Atrial fibrillation (AF) is the most common sustained form of arrhythmia, affecting approximately 3 % of the adult population. AF may be symptomatic or asymptomatic. Asymptomatic paroxysmal atrial fibrillation (PAF) can be troublesome to diagnose, as most devices for arrhythmia detection provide only limited insight into heart rhythm. LÄS MER

  5. 25. Methodological aspects on carotid artery intervention

    Författare :Magnus Jonsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :carotid artery stenosis;

    Sammanfattning : In Sweden, approximately 25000 patients suffer a cerebral infarction (stroke) annually. Stroke ranks as the third-leading cause of death, and is the leading cause of functional impairment. Carotid artery stenosis accounts for approximately 15% of all strokes and almost all of these are theoretically preventable. LÄS MER
