  1. 1. Connecting CMR and Physiology : Expanding the capabilities of cardiovascular magnetic resonance in quantifying physiology

    Författare :Felicia Seemann; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulär magnetresonanstomografi; Fysiologi; Atrioventrikulär klaffplansrörlighet; Mitralisflöde; Tryck-volym loopar; Kraft-längd loopar; Cardiovascular magnetic resonance; Physiology; Atrioventricular plane displacement; Transmitral flow; pressure-volume loops; Ventricular force-length loops;

    Sammanfattning : The assessment of cardiovascular physiology is crucial to facilitate clinical diagnostics, treatment, and research. Physiology and anatomy can be assessed noninvasively using cardiovascular magnetic resonance (CMR), a versatile and reliable medical imaging modality free from ionizing radiation. LÄS MER

  3. 2. Applications of the golden angle in cardiovascular MRI

    Författare :Alexander Fyrdahl; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The use of radial trajectories has been seen as a potential solution to highly efficient cardiovascular magnetic resonance imaging (MRI). By acquiring a broad range of spatial frequencies per repetition time, the acquisition is time-efficient and robust against motion. LÄS MER

  4. 3. Pulmonary hypertension and heart failure : physiological markers assessed by cardiovascular magnetic resonance

    Författare :João Ramos; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Pulmonary hypertension (PH) is clinically and physiologically associated with heart failure, both with reduced and preserved ejection fraction (HFrEF and HFpEF). In HFpEF, the most likely underlying pathophysiological mechanism is an impairment of left ventricular relaxation named diastolic dysfunction. LÄS MER

  5. 4. Prognostic and diagnostic value of tissue Doppler in patients with systolic heart failure

    Författare :Jens Olson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Heart failure;

    Sammanfattning : Heart failure (HF) is a condition where the heart fails to meet the need of delivery of oxygen and energy to the tissues. In spite of advances in the recent decades, the prognosis is still serious with a mortality risk comparable to severe cancer. The most common heart imaging method today is ultrasound of the heart, or echocardiography. LÄS MER

  7. 5. Ventricular Long Axis Function: Amplitudes and Timings : Echocardiographic Studies in Health and Disease

    Författare :Frederick Bukachi; Anders Waldenstrom; Derek Gibson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Echocardiography; Doppler Tissue Imaging; Ageing; coronary disease; left ventricular function; atrial contraction; electromechanical function; coronary angioplasty.; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; kardiologi; Cardiology;

    Sammanfattning : Background: The ageing process not only increases the risk of coronary artery disease (CAD) but also complicates its diagnosis and treatment. It is therefore important to understand the newer concepts of cardiovascular ageing physiology as well as methods of predicting the outcomes of therapeutic options available for the elderly with severe CAD.
