      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 atlas for assessing the impact of tumor location on perioperative quality of life in patients with high-grade glioma: A prospective population-based cohort study 

      Sagberg, Lisa Millgård; Iversen, Daniel Høyer; Fyllingen, Even Hovig; Jakola, Asgeir Store; Reinertsen, Ingerid; Solheim, Ole (Journal article; Peer reviewed, 2019)
      Background Tumor location is important for surgical decision making. Particular attention is paid to regions that contain sensorimotor and language functions, but it is unknown if these are the most important regions from ...
    • Glioblastoma Surgery Imaging-Reporting and Data System: Validation and Performance of the Automated Segmentation Task 

      Bouget, David Nicolas Jean-Marie; Eijgelaar, Roelant; Pedersen, André; Kommers, Ivar; Ardon, Hilko; Barkhof, Frederik; Bello, Lorenzo; Berger, Mitchel S.; Nibali, Marco Conti; Furtner, Julia; Fyllingen, Even Hovig; Hervey-Jumper, Shawn; Idema, Albert J.

      For patients with presumed glioblastoma, essential tumor characteristics are determined from preoperative MR images to optimize the treatment strategy. This procedure is time-consuming and subjective, if performed by crude ...
    • Glioblastoma Surgery Imaging—Reporting and Data System: Standardized Reporting of Tumor Volume, Location, and Resectability Based on Automated Segmentations 

      Kommers, Ivar; Bouget, David Nicolas Jean-Marie; Pedersen, André; Eijgelaar, Roelant; Ardon, Hilko; Barkhof, Frederik; Bello, Lorenzo; Berger, Mitchel S.; Nibali, Marco Conti; Furtner, Julia; Fyllingen, Even Hovig; Hervey-Jumper, Shawn; Idema, Albert J.

(Peer reviewed; Journal article, 2021)
      Treatment decisions for patients with presumed glioblastoma are based on tumor characteristics available from a preoperative MR scan. Tumor characteristics, including volume, location, and resectability, are often estimated ...
    • Spatial distribution of malignant transformation in patients with low-grade glioma 

      Jakola, Asgeir S; Bouget, David Nicolas Jean-Marie; Reinertsen, Ingerid; Skjulsvik, Anne Jarstein; Sagberg, Lisa Millgård; Bø, Hans Kristian; Gulati, Sasha; Sjåvik, Kristin; Solheim, Ole (Peer reviewed; Journal article, 2020)
      Background Malignant transformation represents the natural evolution of diffuse low-grade gliomas (LGG). This is a catastrophic event, causing neurocognitive symptoms, intensified treatment and premature death. However, ...
