    • A new acoustic coupling fluid with ability to reduce ultrasound imaging artefacts in brain tumour surgery - a phase I study 

      Unsgård, Geirmund; Sagberg, Lisa Millgård; Muller, Sebastien; Selbekk, Tormod (Journal article; Peer reviewed, 2019)
      Background Anovel acoustic coupling fluid (ACF), with the potential to reduce surgically induced image artefacts during intraoperative ultrasound imaging in brain tumour surgery, has been evaluated with respect to image ...

    • Animal study assessing safety of an acoustic coupling fluid that holds the potential to avoid surgically induced artifacts in 3D ultrasound guided operations 

      Jakola, Asgeir S; Jørgensen, Arve; Selbekk, Tormod; Michler, Ralf-Peter; Solheim, Ole; Torp, Sverre Helge; Sagberg, Lisa Millgård; Aadahl, Petter; Unsgård, Geirmund (Journal article; Peer reviewed, 2014)
      Background Use of ultrasound in brain tumor surgery is common. The difference in attenuation between brain and isotonic saline may cause artifacts that degrade the ultrasound images, potentially affecting resection grades ...

    • Are there predilection sites for intracranial meningioma? A population-based atlas 

      Hosainey, Sayied Abdol Mohieb; Bouget, David; Reinertsen, Ingerid; Sagberg, Lisa Millgård; Torp, Sverre Helge; Jakola, Asgeir Store; Solheim, Ole (Peer reviewed; Journal article, 2021)
      Meningioma is the most common benign intracranial tumor and is believed to arise from arachnoid cap cells of arachnoid granulations. We sought to develop a population-based atlas from pre-treatment MRIs to explore the ...

    • Brain infarctions after glioma surgery: prevalence, radiological characteristics and risk factors 

      Strand, Per Sveino; Berntsen, Erik Magnus; Fyllingen, Even Hovig; Sagberg, Lisa Millgård; Reinertsen, Ingerid; Gulati, Sasha; Bouget, David; Solheim, Ole (Peer reviewed; Journal article, 2021)
      Background: Prevalence, radiological characteristics, and risk factors for peritumoral infarctions after glioma surgery are not much studied. In this study, we assessed shape, volume, and prevalence of peritumoral infarctions ...

    • Effect of Spinal Cord Burst Stimulation vs Placebo Stimulation on Disability in Patients With Chronic Radicular Pain After Lumbar Spine Surgery: A Randomized Clinical Trial 

      Hara, Sozaburo; Andresen, Hege; Solheim, Ole; Carlsen, Sven Magnus; Sundstrøm, Terje; Lønne, Greger; Vangen-Lønne, Vetle; Taraldsen, Kristin; Tronvik, Erling Andreas; Øie, Lise Rystad; Gulati, Agnete Malm; Sagberg, Lisa Millgård; Jakola, Asgeir Store; Solberg, Tore; Nygaard, Øystein Petter; Salvesen, Øyvind; Gulati, Sasha (Peer reviewed; Journal article, 2022)
      Importance: The use of spinal cord stimulation for chronic pain after lumbar spine surgery is increasing, yet rigorous evidence of its efficacy is lacking. Objective: To investigate the efficacy of spinal cord burst ...

    • Intraoperative risk factors for peritumoral infarctions following glioma surgery 

      Strand, Per Sveino; Gulati, Sasha; Sagberg, Lisa Millgård; Solheim, Ole (Peer reviewed; Journal article, 2022)
      Background Surgical intraoperative risk factors for peritumoral infarctions are not much studied. In the present study, we explore the possible association between intraoperative factors and infarctions diagnosed from ...

    • Perioperative fatigue in patients with diffuse glioma 

      Schei, Stine; Solheim, Ole; Jakola, Asgeir S; Sagberg, Lisa Millgård (Peer reviewed; Journal article, 2020)
      Purpose Few studies have assessed fatigue in relation to glioma surgery. The purpose of this study was to explore the prevalence of pre- and postoperative high fatigue, perioperative changes, and factors associated with ...

    • Primary versus recurrent surgery for glioblastoma-a prospective cohort study 

      Rubin, Maja Chava; Sagberg, Lisa Millgård; Jakola, Asgeir S; Solheim, Ole (Peer reviewed; Journal article, 2020)
      Background: There is currently limited evidence for surgery in recurrent glioblastoma (GBM). Our aim was to compare primary and recurrent surgeries, regarding changes in perioperative, generic health-related quality of ...

    • Segmentation of glioblastomas in early post-operative multi-modal MRI with deep neural networks 

      Helland, Ragnhild Holden; Ferles, Alexandros; Pedersen, Andre; Kommers, Ivar; Ardon, Hilko; Barkhof, Frederik; Bello, Lorenzo; Berger, Mitchel S.; Dunås, Tora; Nibali, Marco Conti; Furtner, Julia; Hervey-Jumper, Shawn; Idema, Albert J.
