  1. 11. Current diagnostic aspects on acute and chronic pulmonary embolism : MRI in acute pulmonary embolism, CT in chronic thromboembolic pulmonary hypertension and what the radiologists actually know

    Författare :Anna Nordgren Rogberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Acute pulmonary embolism (APE) is a potentially severe medical condition with blood clots obstructing the pulmonary arterial vasculature. In most cases the APE resolves without any sequelae after anticoagulation therapy. LÄS MER

  3. 12. Computed Tomography of the Coronary Arteries : Developmental and Prognostic Investigations

    Författare :Mårten Sandstedt; Anders Persson; Joakim Alfredsson; Magnus Janzon; Jan Engvall; Mats Lidén; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Computed tomography (CT) is an increasingly used modality for investigations of patients with suspected coronary artery disease (CAD). Technical advances could improve diagnostic accuracy and lead to clinical workflow improvements. Also, more prognostic information can optimize clinical follow-up strategies and treatments. LÄS MER

  4. 13. Low kilovoltage computed tomography to reduce contrast medium dose in patients at risk of acute kidney injury

    Författare :Fredrik Holmquist; Lund Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Computed tomography; Image quality; Radiation dosimetry; contrast medium induced nephropathy; Iterative reconstruction algorithms;

    Sammanfattning : Background: Patients with reduced renal function may be at risk of contrast medium-induced acute kidney injury (CI-AKI) following intravenous iodine contrast medium (CM) enhanced computed tomography (CT). Reducing the CM dose may reduce this risk. LÄS MER

  5. 14. Optimization of image quality and radiation dose in neuroradiological computed tomography

    Författare :Askell Löve; Lund Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Background: The goal of clinical computed tomography (CT) is to produce images of diagnostic quality using the lowest possible radiation exposure. Degradation of image quality, with increased image noise and reduced spatial resolution, is a major limitation for radiation dose reduction in CT. LÄS MER

  7. 15. Assessing and minimizing risk of patients with aortic disease

    Författare :Roberta Vaccarino; Vaskulära sjukdomar - kliniska studier; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vascular diseases; Aortic disease; aortic aneurysm; risk assessment;

    Sammanfattning : Prophylactic endovascular aneurysm repair (EVAR) of abdominal aortic aneurysm (AAA) aims to avoid aneurysm rupture. However, only patients with sufficient long-term survival get benefit from this avoidance. Therefore, accurate patient selection is crucial. LÄS MER
