  2. 1. Multidimensional MRI of Cardiac Motion : Acquisition, Reconstruction and Visualization

    Author : Andreas Sigfridsson; Hans Knutsson; Stefan Skare; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MRI; cardiac; motion; reconstruction; Image analysis; Bildanalys;

    Abstract : Methods for measuring deformation and motion of the human heart in-vivo are crucial in the assessment of cardiac function. Applications ranging from basic physiological research, through early detection of disease to follow-up studies, all benefit from improved methods of measuring the dynamics of the heart. READ MORE

  4. 2. Quantitative cardiac 15O-water PET : Assessment of left-ventricular function, remodeling, and impact of patient motion

    Author : Jonny Nordström; Mark Lubberink; Jens Sörensen; Hendrik J Harms; Stephan Nekolla; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; positron emission tomography PET ; 15O-water; myocardial blood flow; cardiac remodeling; patient motion;

    Abstract : International guidelines advocate the use of noninvasive cardiac imaging as the initial diagnostic test for coronary artery disease, the global leading cause of death according to the world health organization. Within the wide spectrum of cardiac imaging, 15O-water PET is the gold standard for noninvasive quantification of myocardial blood flow (MBF). READ MORE

  5. 3. Annular Motion : Assessment of Cardiac Function using Echocardiography and Magnetic Resonance Imaging

    Author : Lena Lindström; Otto Smiseth; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : This thesis concentrates on the assessment of cardiac function, both systolic and diastolic using variables originating from the longitudinal motion of the heart using both established and novel non-invasive imaging techniques. We developed a new magnetic resonance imaging (MRI) technique that creates an M-mode MRI image, analogous to the one used in echocardiography and enables quantitative assessment of cardiac motion.

  6. 4. Ventricular rotation and the rotation axis : a new concept in cardiac function

    Author : Ulf Gustafsson; Anders Waldenström; Per Lindqvist; Alan Fraser; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Left ventricular function; right ventricular function; rotation; twist; rotation axis; transition plane; ischemia; speckle tracking echocardiography; Cardiology; Kardiologi; Cardiology; kardiologi;

    Abstract : Background: The twisting motion of the left ventricle (LV), with clockwise rotation at the base and counter clockwise rotation at the apex during systole, is a vital part of LV function. Even though LV rotation has been studied for decades, the rotation pattern has not been described in detail. READ MORE

  7. 5. Left ventricular dysfunction in critically ill patients

    Author : Oscar Cavefors; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Left ventricular dysfunction; Left ventricular diastolic dysfunction; hsTNT; NT-proBNP; Coronary angiography; Regional wall motion abnormalities; Takotsubo syndrome; Septic cardiomyopathy; MINOCA; Cardiac disease; Intensive care unit; Echocardiography;

    Abstract : ABSTRACT Background: Cardiac dysfunction is common in Intensive Care Unit (ICU) patients and can contribute to multiorgan failure and death. Despite this, few studies have been performed on pathogenies, prevalence, diagnosis and impact on mortality in unselected ICU patients. READ MORE
