  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. Combining Shape and Learning for Medical Image Analysis

    Author : Jennifer Alvén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; feature-based registration; convolutional neural networks; conditional random fields; medical image segmentation; random decision forests; machine learning; multi-atlas segmentation; medical image registration; shape models;

    Abstract : Automatic methods with the ability to make accurate, fast and robust assessments of medical images are highly requested in medical research and clinical care. Excellent automatic algorithms are characterized by speed, allowing for scalability, and an accuracy comparable to an expert radiologist. READ MORE

  5. 3. On the use of computed tomography in cardiac imaging

    Author : Jakob De Geer; Anders Persson; Jan Engvall; Michael Sandborg; Örjan Smedby; Åse Johnsson; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : BackgroundCardiac Computed Tomography Angiography (CCTA) is becoming increasingly useful in the work‐up of coronary artery disease (CAD). Several potential methods for increasing the diagnostic yield of cardiac CT are available. READ MORE

  6. 4. 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

  7. 5. Aspects of regular long-term endurance exercise in adolescents, with focus on cardiac size and function, hormones, and the immune system

    Author : Louise Rundqvist; Maria Faresjö; Peter Blomstrand; Katarina Steding-Ehrenborg; Jönköping University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adolescence; endurance-trained; cardiac dimension; cardiac systolic function; cardiac diastolic function; growth hormone; immune response; echocardiography; biomarkers; cytokines; chemokines; insulin-like growth factor 1; type 1 diabetes-related autoantigen; proinsulin;

    Abstract : The long-term effects of starting high-intensity training at younger ages are largely unknown. The present studies focused on adolescents who had performed regular endurance exercise for several years at an elite level and compared those subjects with a control group of adolescents of similar age and sex who had not engaged in regular exercise.
