    • Magnetisk resonanstomografi i multisenterstudier. Objektiv og subjektiv evaluering av bildekvalitet 

      Nakken, Ingeborg Elise (Master thesis, 2011-12-05)
      Background: Magnetic resonance imaging (MRI) is a technically vulnerable acquisition method. Sequence optimization across equipment increase image quality and reproducibility of multicenter data. Comparisons of scanner-related ...

    • Multimodal imaging of gliomas in the context of evolving cellular and molecular therapies 

      Keunen, Olivier; Taxt, Torfinn; Grüner, Renate; Lund-Johansen, Morten; Tonn, Joerg-Christian; Pavlin, Tina; Bjerkvig, Rolf; Niclou, Simone P.; Thorsen, Frits Alan (Peer reviewed; Journal article, 2014-09-30)
      The vastmajority ofmalignant gliomas relapse after surgery and standard radio-chemotherapy. Novelmolecular and cellular therapies are thus being developed, targeting specific aspects of tumor growth.While histopathology ...

    • No effect of 6-month intake of glucosamine sulfate on Modic changes or high intensity zones in the lumbar spine: sub-group analysis of a randomized controlled trial 

      Wilkens, Philip; Storheim, Kjersti; Scheel, Inger; Berg, Linda; Espeland, Ansgar (Peer reviewed; Journal article, 2012-08-17)
      Background: The underlying pathology and natural course of Modic changes (MC) in the vertebral body marrow and high intensity zones (HIZs) in the annulus fibrosus is not completely clarified. These findings on magnetic ...

    • A novel nanoprobe for multimodal imaging is effectively incorporated into human melanoma metastatic cell lines 

      Aasen, Synnøve Nymark; Pospíšilová, Aneta; Eichler, Tilo Wolf; Pánek, Jiří; Hrubý, Martin; Štěpánek, Petr; Spriet, Endy; Jirák, Daniel; Skaftnesmo, Kai Ove; Thorsen, Frits (Peer reviewed; Journal article, 2015-09-08)
      To facilitate efficient drug delivery to tumor tissue, several nanomaterials have been designed, with combined diagnostic and therapeutic properties. In this work, we carried out fundamental in vitro and in vivo experiments ...
