  1. 1. Quantification of 4D Left Ventricular Blood Flow in Health and Disease

    Author : Jonatan Eriksson; Tino Ebbers; Carl-Johan Carlhäll; Gianni Pedrizzetti; Linköpings universitet; []
    Keywords : MRI; relative pressure; 4D flow; quantification; turbulent kinetic energy; dilated cardiomyopathy; magnetic resonance imaging; physiology; cardiac function; diastolic dysfunction;

    Abstract : The main function of the heart is to pump blood throughout the cardiovascular system by generating pressure differences created through volume changes. Although the main purpose of the heart and vessels is to lead the flowing blood throughout the body, clinical assessments of cardiac function are usually based on morphology, approximating the flow features by viewing the motion of the myocardium and vessels.

  2. 2. Towards Personalized Models of the Cardiovascular System Using 4D Flow MRI

    Author : Belén Casas Garcia; Tino Ebbers; Jonas Lantz; Petter Dyverfeldt; Carljohan Carlhäll; Frans van de Vosse; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; 4D Flow MRI; Computational modelling; Blood flow; Hemodynamics;

    Abstract : Current diagnostic tools for assessing cardiovascular disease mostly focus on measuring a given biomarker at a specific spatial location where an abnormality is suspected. However, as a result of the dynamic and complex nature of the cardiovascular system, the analysis of isolated biomarkers is generally not sufficient to characterize the pathological mechanisms behind a disease.

  3. 3. Automated Assessment of Blood Flow in the Cardiovascular System Using 4D Flow MRI

    Author : Mariana Bustamante; Tino Ebbers; Carljohan Carlhäll; Petter Dyverfeldt; Michael Markl; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; 4D Flow MRI; Image Analysis; Segmentation;

    Abstract : Medical image analysis focuses on the extraction of meaningful information from medical images in order to facilitate clinical assessment, diagnostics and treatment. Image processing techniques have gradually become an essential part of the modern health care system, a consequence of the continuous technological improvements and the availability of a variety of medical imaging techniques.

  4. 4. 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. 5. Fast and Accurate 4D Flow MRI for Cardiovascular Blood Flow Assessment

    Author : Sven Petersson; Tino Ebbers; Oliver Wieben; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The study of blood flow is essential in understanding the physiology and pathophysiology of the cardiovascular system. Small disturbances of the blood flow may over time evolve and contribute to cardiovascular pathology. READ MORE
