  2. 1. Hyperemic Brachial Artery Blood Flow Velocity

    Author : Susann J Järhult; Lars Lind; Johan Sundström; Peter Friberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN; Cardiovascular medicine; Kardiovaskulär medicin; Medicinsk vetenskap; Medical Science;

    Abstract : This thesis aims to evaluate the blood flow velocity in the Brachial artery during reactive hyperemia. Primarily to appraise the information it might contain regarding cardiovascular function and cardiovascular risk. READ MORE

  4. 2. Blood flow specific assessment of ventricular function : Visualization and quantification using 4D flow CMR

    Author : Alexandru Grigorescu Fredriksson; Carljohan Carlhäll; Bengt Johansson; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : 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.

  5. 3. Physiological aspects on intracardiac blood flow

    Author : Per Arvidsson; Lund Klinisk fysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance imaging; 4D flow; physiology; cardiac development; kinetic energy; hemodynamic force; vortex ring formation;

    Abstract : 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.

  6. 4. On Aortic Blood Flow Simulations : Scale-Resolved Image-Based CFD

    Author : Jonas Lantz; Matts Karlsson; Shawn Shadden; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : 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.

  7. 5. Regulation of Microvascular Blood Flow : a clinical and experimental study based on laser Doppler perfusion imaging

    Author : Helena Golster; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Local blood flow reflexes in the foot skin of healthy controls and in young diabetic patients with or without nerve dysfunction have been studied using laser Doppler perfusion imaging (LDPI). A neurophysiological follow-up study on nerve dysfunction is presented as a complerhent to the work on blood flow regulation in the young diabetics. READ MORE
