• Iterative reconstruction improves image quality and reduces radiation dose in trauma protocols; A human cadaver study 

      Godt, Johannes Jakob Clemens; Johansen, Cathrine K.; Martinsen, Anne Catrine Trægde; Schulz, Anselm; Brøgger, Helga Maria; Jensen, Kristin; Stray-Pedersen, Arne; Dormagen, Johann Baptist (Acta Radiologica Open;Volume: 10, issue: 10, Peer reviewed; Journal article, 2021-11-18)
      Background: Radiation-related cancer risk is an object of concern in CT of trauma patients, as these represent a young population. Different radiation reducing methods, including iterative reconstruction (IR), and spilt ...
    • Short tau inversion recovery MRI of Modic changes: a reliability study 

      Kristoffersen, Per M; Vetti, Nils; Storheim, Kjersti; Bråten, Lars Christian Haugli; Rolfsen, Mads Peder; Assmus, Jörg; Espeland, Ansgar (Acta Radiologica Open;Volume: 9, issue: 1, Journal article; Peer reviewed, 2020-01-29)
      Background: Limited reliability data exist for evaluation of spinal edema changes on magnetic resonance imaging (MRI) with short tau inversion recovery (STIR) sequences. Purpose: To assess the inter-observer reliability ...
    • A survey of local diagnostic reference levels for the head, thorax, abdomen and pelvis computed tomography in Norway and Canada 

      Johansen, Safora (Acta Radiologica Open;Volume 11, Issue 10, Peer reviewed; Journal article, 2022-10-07)
      Background: Computed tomography (CT) contributes to 60% of the collective dose in medical imaging. Literature has demonstrated that patient dose varies across regions and countries. Establishing diagnostic reference levels ...
    • Ultra-low-dose emergency chest computed tomography protocols in three vendors: A technical note 

      Mussmann, Bo; Skov, Peter Marshall; Lorentzen, Morten Hjarnø; Skjøt-Arkil, Helene; Graumann, Ole; Andersen, Michael Bruun; Jensen, Janni (Peer reviewed; Journal article, 2023)
      Background: In suspected community-acquired pneumonia (CAP), chest CT is superior to the routinely obtained radiographs (CXR), but administers higher radiation doses. However, ultra-low-dose CT (ULDCT) has shown ...
