  1. 1. Tissue Doppler in Spectral and Color ModeMethodological ConsiderationsNon-invasive Estimation of Left Ventricular Filling Pressures using the E/Em index

    Författare :Aristomenis Manouras; Lars Åke Brodin; Michael Henein; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tissue Doppler; Cardiology; Kardiologi;

    Sammanfattning : Aims: Tissue Doppler (TD) in spectral mode (spectral TD) and color TD are the two modalities available today in tissue velocity echocardiography (TVE). Measurements of left ventricular (LV) myocardial velocities and displacement may yield different results depending on the employed sonographic modality and the subjective adjustments during data analysis.

  3. 2. Non-invasive ultrasound-based cardiovascular imaging in mouse models of atherosclerosis

    Författare :Julia Grönros; Göteborgs universitet; []
    Nyckelord :atherosclerosis; ultrasound-based imaging; cardiovascular disease; coronary artery; mouse; color Doppler echocardiography; ultrasound biomicroscopy; statin;

    Sammanfattning : Atherosclerosis is a chronic multi-factorial vascular disease. It generally requires large clinical settings and over many years to study the disease progression in man. Genetically modified mouse models of atherosclerosis have dramatically increased research feasibility within this area. LÄS MER

  4. 3. On Nonlinear Acoustics in Contrast Echocardiography

    Författare :Marcus Ressner; Birgitta Janerot-Sjöberg; Per Ask; Tomas Jansson; Hans Torp; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Ultrasound is one of the most commonly used noninvasive medical imaging techniques. Ultrasound contrast agents (UCA), consisting of encapsulated gas-filled microbubbles, have shown to increase the diagnostic precision in selected low echogenic patients. LÄS MER

  5. 4. The right ventricle in volume or pressure overload : Insights from novel imaging techniques

    Författare :Aleksandra Trzebiatowska-Krzynska; Eva Swahn; Niels Erik Nielsen; Lars Wallby; Marcus Carlsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : This study is inspired by the gap in knowledge regarding the timing of cardiac surgery and interventions in adult patients with congenital heart disease. There are many parameters used assessing right ventricular function; however, most of them have pitfalls. LÄS MER
