  • Correlations between measures of executive attention and cortical thickness of left posterior middle frontal gyrus - a dichotic listening study 

    Andersson, Martin; Ystad, Martin; Lundervold, Arvid; Lundervold, Astri Johansen (BioMed Central, 2009-10-01)
    Background: The frontal lobe has been associated to a wide range of cognitive control functions and is also vulnerable to degeneration in old age. A recent study by Thomsen and colleagues showed a difference between a ...
  • Generating a synthetic diffusion tensor dataset 

    Bergmann, Ørjan; Lundervold, Arvid; Steihaug, Trond (IEEE, 2005)
    During the last years, many techniques for de-noising, segmentation and fiber-tracking have been applied to diffusion tensor MR image data (DTI) from human and animal brains. However, evaluating such methods may be difficult ...
  • Normalized gradient fields for nonlinear motion correction of DCE-MRI time series 

    Hodneland, Erlend; Lundervold, Arvid; Rørvik, Jarle; Munthe-Kaas, Antonella Zanna (ElsevierComputerized Medical Imaging Society, 2014-04)
    Dynamic MR image recordings (DCE-MRI) of moving organs using bolus injections create two differenttypes of dynamics in the images: (i) spatial motion artifacts due to patient movements, breathing andphysiological pulsations ...
  • Post-adolescent developmental changes in cortical complexity 

    Sandu, Anca-Larisa; Izard, Edouard; Specht, Karsten; Beneventi, Harald; Lundervold, Arvid; Ystad, Martin (BioMed Central, 2014-11-27)
    Background: Post-adolescence is known to be a period of general maturation and development in the human brain. In brain imaging, volumetric and morphologic cortical grey-matter changes can easily be assessed, but the ...
  • Random Forest ensembles for detection and prediction of Alzheimer's disease with a good between-cohort robustness 

    Lebedev, Alexander; Westman, Eric; Westen, G. J. P. Van; Kramberger, M. G.; Lundervold, Arvid; Aarsland, Dag; Soininen, H.; Kłoszewska, I.; Mecocci, P.; Tsolaki, M.; Vellas, B.; Lovestone, S.; Simmons, Andrew (Elsevier, 2014)
    Computer-aided diagnosis of Alzheimer's disease (AD) is a rapidly developing field of neuroimaging with strong potential to be used in practice. In this context, assessment of models' robustness to noise and imaging ...
  • Segmentation-Driven Image Registration-Application to 4D DCE-MRI Recordings of the Moving Kidneys 

    Hodneland, Erlend; Hanson, Erik Andreas; Lundervold, Arvid; Modersitzki, Jan; Eikefjord, Eli Bjøvad; Zanna, Antonella (IEEE, 2014-04-01)
    Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) of the kidneys requires proper motion correction and segmentation to enable an estimation of glomerular filtration rate through pharmacokinetic modeling. ...
