    • Is intracranial volume a risk factor for IDH-mutant low-grade glioma? A case-control study 

      Sagberg, Lisa Millgård; Fyllingen, Even Hovig; Hansen, Tor Ivar; Strand, Per Sveino; Håvik, Aril Løge; Sundstrøm, Terje; Corell, Alba; Jakola, Asgeir Store; Salvesen, Øyvind; Solheim, Ole (Journal article; Peer reviewed, 2022)
      Purpose Risk of cancer has been associated with body or organ size in several studies. We sought to investigate the relationship between intracranial volume (ICV) (as a proxy for lifetime maximum brain size) and risk of ...

      Dybvik, Julie Andrea; Fasmer, Kristine Eldevik; Ytre-Hauge, Sigmund; Husby, Jenny Hild Aase; Salvesen, Øyvind; Stefansson, Ingunn Marie; Krakstad, Camilla; Trovik, Jone; Haldorsen, Ingfrid S. (Journal article; Peer reviewed, 2022)
      Objectives To explore the diagnostic accuracy of preoperative magnetic resonance imaging (MRI)-derived tumor measurements for the prediction of histopathological deep (≥ 50%) myometrial invasion (pDMI) and prognostication ...

    • Preoperative 18F-FDG PET/CT tumor markers outperform MRI-based markers for the prediction of lymph node metastases in primary endometrial cancer 

      Fasmer, Kristine Eldevik; Gulati, Ankush; Dybvik, Julie Andrea; Ytre-Hauge, Sigmund; Salvesen, Øyvind; Trovik, Jone; Krakstad, Camilla; Haldorsen, Ingfrid S. (Journal article; Peer reviewed, 2020)
      Objectives To compare the diagnostic accuracy of preoperative 18F-FDG PET/CT and MRI tumor markers for prediction of lymph node metastases (LNM) and aggressive disease in endometrial cancer (EC). Methods Preoperative ...

    • Preoperative pelvic MRI and 2-[18F]FDG PET/CT for lymph node staging and prognostication in endometrial cancer—time to revisit current imaging guidelines? 

      Fasmer, Kristine Eldevik; Gulati, Ankush; Dybvik, Julie Andrea; Wagner-Larsen, Kari Strøno; Lura, Njål Gjærde; Salvesen, Øyvind; Forsse, David Erik; Trovik, Jone; Pijnenborg, Johanna M. A.; Krakstad, Camilla; Haldorsen, Ingfrid S. (Journal article; Peer reviewed, 2022)

    • Preoperative tumor size at MRI predicts deep myometrial invasion, lymph node metastases, and patient outcome in endometrial carcinomas 

      Ytre-Hauge, Sigmund; Husby, Jenny Hild Aase; Magnussen, Inger Johanne; Werner, Henrica Maria Johanna; Salvesen, Øyvind; Bjørge, Line; Trovik, Jone; Stefansson, Ingunn; Salvesen, Helga Birgitte; Haldorsen, Ingfrid S. (Peer reviewed; Journal article, 2015)
      OBJECTIVE: The aim of this study was to explore the relation between preoperative tumor size based on magnetic resonance imaging (MRI) and the surgical pathologic staging parameters (deep myometrial invasion, cervical ...

    • Tumour texture features from preoperative CT predict high-risk disease in endometrial cancer
