3D ultrasound-guided resection of low-grade gliomas: principles and clinical examples
Unsgård, Geirmund; Lindseth, Frank (Journal article, 2019)3D ultrasound (US) is a convenient tool for guiding the resection of low-grade gliomas, seemingly without deterioration in patients’ quality of life. This article offers an update of the intraoperative workflow and the ... -
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 ... -
Comparison of contrast in brightness mode and strain ultrasonography of glial brain tumours
Selbekk, Tormod; Brekken, Reidar; Indergaard, Marit Kristina; Solheim, Ole; Unsgård, Geirmund (Journal article; Peer reviewed, 2012)Background Image contrast between normal tissue and brain tumours may sometimes appear to be low in intraoperative ultrasound. Ultrasound imaging of strain is an image modality that has been recently explored for ...
