  1. 1. Intravenous contrast media optimization at computed tomography

    Författare :Anders Svensson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The administration of intravenous contrast media (IV CM) is essential for detecting lesions at most computed tomography (CT) examinations. The overall aim of this thesis is to investigate different aspects of IV CM administration that may affect the quality of the CT examination. LÄS MER

  4. 3. Optimizing computed tomography : quality assurance, radiation dose and contrast media

    Författare :Patrik Nowik; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Computed tomography (CT) is an important modality in radiology; it enables imaging of the inside of patients without superimposed anatomy. The radiation dose and quality of a CT image are highly dependent on the CT scanner, the scan settings and, if applicable, the timing and dosage of the intravenous contrast media (CM). LÄS MER

  5. 4. Blood Pressure Elevation - Impact on Cardiovascular Structure and Endogenous Fibrinolysis

    Författare :Wilhelm Ridderstråle; Göteborgs universitet; []
    Nyckelord :hypertension; left ventricular hypertrophy; intima-media thickness; fibrinolysis; endothelium; tissue plasminogen activator; antihypertensive agents; mechanical stress; plasminogen activator inhibitor-1;

    Sammanfattning : Blood pressure elevation is a major risk factor for cardiovascular events and the risk increases in a dose-dependant manner. It is of importance to identify subjects prone to develop hypertension and adverse cardiovascular remodeling in order to start treatment timely. LÄS MER

  7. 5. MRI sequences for detection of acute pulmonary embolism

    Författare :Roberto Vargas Paris; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In recent years a range of imaging techniques have emerged to help diagnose patients with suspected acute Pulmonary Embolism (PE). This is particularly useful for those who are contraindicated (renal failure or allergies) to the contrast media that is needed to perform Computed Tomography Pulmonary Angiography (CTPA), which would be the usual diagnostic tool of choice.
