  2. 11. Splanchnic perfusion in cardiac surgery

    Author : Anders Thorén; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Splanchnic circulation; jejunal mucosal perfusion; laser Doppler flowmetry; cardiopulmonary bypass; cardiac surgery; inotropic agents; gastric tonometry; sympathetic reflex;

    Abstract : Splanchnic ischemia in cardiac surgery is considered a risk factor in the development of the Multiple Organ Dysfunction Syndrome (MODS), which is the leading cause of morbidity and mortality in the intensive care unit. Splanchnic ischemia/reperfusion may lead to an injury of the intestinal mucosa and induce a systemic inflammation (SIRS), which is proposed to precede MODS. READ MORE

  4. 12. NMR Imaging of Flow and Perfusion using Hyperpolarized Nuclei: Theoretical Considerations and Application to Experimental Models

    Author : Edvin Johansson; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nukleärmedicin; radiobiologi; radiobiology; Nuclear medicine; Perfusion; Macroscopic flow; Hyperpolarized tracers; Nuclear magnetic resonance NMR ; Magnetic resonance imaging MRI ;

    Abstract : In the studies presented in this thesis, hyperpolarized tracers have been used for the study of macroscopic flow and capillary perfusion with magnetic resonance imaging. The feasibility of performing vascular studies using echo-planar imaging (EPI) and hyperpolarized 129Xe was investigated using xenon dissolved in ethanol prior to injection into a flow phantom.

  5. 13. Cerebral CT - and MRI perfusion: Techniques and clinical application in iNPH

    Author : Doerthe Ziegelitz; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cerebral perfusion; idiopathic normal pressure hydrocephalus; computed tomography perfusion; dynamic suceptibility contrast MRI;

    Abstract : Idiopathic normal pressure hydrocephalus (iNPH) is a disorder of the elderly, defined by slowly progressive impairment of gait and balance, cognitive decline, and incontinence. Disturbance of the cerebrospinal fluid (CSF) dynamics results in ventriculomegaly without intracranial pressure increase. READ MORE

  6. 14. Laser Doppler perfusion imaging : methodology and skin applications

    Author : Karin Wårdell; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : 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. READ MORE
