21. Ultrasound evaluation of atherosclerosis and other cardiovascular sources of cerebral embolism
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
22. 4D flow MRI and modelling to assess cerebral arterial hemodynamics : method development and evaluation, with implementation in patients with symptomatic carotid stenosis
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
23. Hereditary risk factors for stroke in humans - Association studies with emphasis on familial and genotypic factors
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
24. Detection of paroxysmal atrial fibrillation : with special emphasis on intermittent ECG recording
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
25. Methodological aspects on carotid artery intervention
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
