1. Laser Doppler perfusion imaging : methodology and skin applications
Sammanfattning : Over the last decade a number of emerging technologies have become available for the non-invasive study of skin anatomy and physiology. In this thesis, a method for mapping tissue perfusion based on the laser Doppler technique is presented together with some of the associated experimental and clinical applications. LÄS MER
2. Non-invasive ultrasound-based cardiovascular imaging in mouse models of atherosclerosis
Sammanfattning : Atherosclerosis is a chronic multi-factorial vascular disease. It generally requires large clinical settings and over many years to study the disease progression in man. Genetically modified mouse models of atherosclerosis have dramatically increased research feasibility within this area. LÄS MER
3. Ultrasonography for Diagnosis, Intervention and Follow-up in Juvenile Idiopathic Arthritis
Sammanfattning : Early therapeutic intervention and the use of novel, highly effective treatments in juvenile idiopathic arthritis (JIA) have improved the outcome in many diseased children, but have also increased the need for more precise methods for evaluating disease activity. In this context, both ultrasonography (US) and magnetic resonance imaging (MRI) play an important role in adult rheumatology, although these methods have yet not been fully evaluated in JIA. LÄS MER
4. Quantification and Visualization of Cardiovascular Function using Ultrasound
Sammanfattning : There is a large need for accurate methods detecting cardiovascular diseases, since they are one of the leading causes of mortality in the world, accounting for 29.3% of all deaths. LÄS MER
5. Clinical Studies on Dark Adaptation: with Particular Reference to Carotid Artery Disease
Sammanfattning : Purpose: To study dark adaptation in patients with symptomatic carotid artery disease or polycythemia before and after treatment. This necessitated determinations of pupillary changes as such may influence the findings. To determine whether changes in the retinal blood flow in light and darkness occur in healthy humans. LÄS MER
