11. Cerebral blood flow and intracranial pulsatility studied with MRI : measurement, physiological and pathophysiological aspects
Sammanfattning : 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. LÄS MER
12. Adipose tissue as an active organ : blood flow regulation and tissue-specific glucocorticoid metabolism
Sammanfattning : Background: Despite advances in the treatment of atherosclerosis, cardiovascular disease is the leading cause of death worldwide. With the population getting older and more obese, the burden of cardiovascular disease may further increase. LÄS MER
13. Blood flow specific assessment of ventricular function : Visualization and quantification using 4D flow CMR
Sammanfattning : The spectrum of cardiovascular diseases is the leading cause of morbidity and mortality globally. Early assessment and treatment of these conditions, acquired as well as congenital, is therefore of paramount importance. The human heart has a great ability to adapt to various hemodynamic conditions by cardiac remodeling. LÄS MER
14. Physiological aspects on intracardiac blood flow
Sammanfattning : Magnetic resonance imaging enables detailed in vivo study of complex flow through 3D, time-resolved phase contrast imaging (4D flow). 4D flow may reveal previously unknown aspects of the physiology of intracardiac blood flow, and possibly elucidate pathophysiological processes that have yet to manifest themselves outside the heart.

15. On Aortic Blood Flow Simulations : Scale-Resolved Image-Based CFD
Sammanfattning : This thesis focuses on modeling and simulation of the blood flow in the aorta, the largest artery in the human body. It is an accepted fact that abnormal biological and mechanical interactions between the blood flow and the vessel wall are involved in the genesis and progression of cardiovascular diseases. LÄS MER
