    • Diabetes mellitus og risikoen for lungekreft, en HUNT-studie 

      Skjerve, Edit Austrheim; Valan, Astrid Balsvik (Master thesis, 2015)
      Bakgrunn Lungekreft er den kreften med høyest mortalitet på verdensbasis, trolig grunnet lite symptomer initialt og følgende sen diagnostisering av sykdom. Man mangler pålitelige risikofaktorer som kan definere en ...
    • Evaluering av PET-CT ved lungekreftutredning - Sammenligning før og etter innføring av PET-CT ved St. Olavs Hospital 

      Bruteig, Johannes Gihle; Ullern, Andreas (Master thesis, 2016)
      Bakgrunn: PET-CT er et viktig verktøy i stadieinndelingen av lungekreft. Inntil høsten 2013 ble alle pasienter fra Midt-Norge sendt til Bergen (Haukeland sykehus) eller Oslo (OUS eller Aleris) for denne undersøkelsen. Etter ...
