    • Contrast medium protocols in routine chest CT:a survey study 

      Henning, Mette Karen; Aaløkken, Trond M; Johansen, Safora (Peer reviewed; Journal article, 2021)
      Background Administration of contrast medium (CM) is an important image quality factor in computed tomography (CT) of the chest. There is no clear evidence or guidelines on CM strategies for chest CT, thus a consensus ...

    • The impact of body compositions on contrast medium enhancement in chest CT: a randomised controlled trial 

      Henning, Mette Karen; Aaløkken, Trond Mogens; Martinsen, Anne Catrine Trægde; Johansen, Safora (Peer reviewed; Journal article, 2023)
      Objective: To compare a fixed-volume contrast medium (CM) protocol with a combined total body weight (TBW) and body composition-tailored protocol in chest CT. Methods and materials: Patients referred for routine contrast ...

    • Impact of iodine concentration and scan parameters on image quality, contrast enhancement and radiation dose in thoracic CT 

      Solbak, Marian S.; Henning, Mette Karen; England, Andrew; Martinsen, Anne Catrine Trægde; Aaløkken, Trond M; Johansen, Safora (European Radiology Experimental;4, Article number: 57 (2020), Journal article; Peer reviewed, 2020-09-11)
      Background: We investigated the impact of varying contrast medium (CM) densities and x-ray tube potentials on contrast enhancement (CE), image quality and radiation dose in thoracic computed tomography (CT) using two ...

    • Strategies for calculating contrast media dose for chest CT 

      Johansen, Safora; Henning, Mette Karen; Gunn, Catherine; Arenas-Jiménez, Juan (Journal article; Peer reviewed, 2023)
      Background Total body weight (TBW) is a frequently used contrast media (CM) strategy for dose calculation in enhanced CT, yet it is suboptimal as it lacks consideration of patient characteristics, such as body fat percentage ...
