  1. 1. 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

  3. 2. Ultrasound based shear wave elastography of the liver : a non-invasive method for evaluation of liver disease

    Författare :Marie Byenfeldt; Anders Elvin; Per Fransson; Odd Helge Gilja; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anthropometric measurement; diagnostic imaging; elasticity imaging technique; blood supply; BMI; body position; fatty liver; liver disease; hepatic steatosis; liver fibrosis; liver stiffness; obesity; postural change; pressure; probe; sex characteristic; shear wave elastography; skin-to-liver capsule distance; transducer and ultrasonography; Radiography; radiografi;

    Sammanfattning : Background: Detecting liver disease at an early stage is important, given that early intervention decreases the risk of developing cirrhosis and subsequently hepatocellular cancer (HCC). The non-invasive ultrasound-based shear wave elastography (SWE) has been used clinically for a decade to assess liver stiffness. LÄS MER

  4. 3. Imaging of coronary artery function and morphology in living mice - applications in atherosclerosis research

    Författare :Johannes Wikström; Göteborgs universitet; []
    Nyckelord :atherosclerosis; coronary artery; coronary flow velocity reserve; imaging; mouse; transthoracic Doppler echocardiography; ultrasound biomicroscopy;

    Sammanfattning : Atherosclerosis in the coronary arteries is the major reason for myocardial infarction and cardiovascular death. In the clinic, several imaging systems make it possible to study coronary artery function and morphology non-invasively, such as transthoracic Doppler echocardiography (TTDE). LÄS MER

  5. 4. Quantification and Visualization of Cardiovascular Function using Ultrasound

    Författare :Matilda Larsson; Lars-Åke Brodin; Hans Torp; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultrasound; Tissue Doppler imaging; Speckle tracking imaging; cardiovascular function; visualization; quantification; Medical engineering; Medicinsk teknik;

    Sammanfattning : There is a large need for accurate methods detecting cardiovascular diseases, since they are one of the leading causes of mortality in the world, accounting for 29.3% of all deaths. LÄS MER

  7. 5. Patterns of non-invasive imaging of carotid atherosclerosis

    Författare :Pranvera Ibrahimi; Michael Henein; Per Wester; Pompilio Faggiano; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiology; kardiologi;

    Sammanfattning : Atherosclerosis is an inflammatory disease that can be generalized, affecting more than one arterial bed simultaneously, or localized, manifested in one system. Ultrasound based measurements of plaque textural features, such as low grey scale median (GSM), echolucent (hypoechoic) plaque types and juxtaluminal black (hypoechoic) area (JBA) are manifestation of potentially unstable lesions.
