    G Karas
    Department of Diagnostic Radiology, VU University Medical Center, Amsterdam, The Netherlands
    AJNR Am J Neuroradiol 29:944-9. 2008
    ..We used voxel-based morphometry (VBM) to find out whether structural differences on MR imaging could offer insight into the development of clinical AD in patients with amnestic MCI at 3-year follow-up...
  2. ncbi A comprehensive study of gray matter loss in patients with Alzheimer's disease using optimized voxel-based morphometry
    G B Karas
    Department of Diagnostic Radiology, Vrije Universiteit Medical Center, Amsterdam, The Netherlands
    Neuroimage 18:895-907. 2003
    ..Moreover, we show atrophy of the caudate head nuclei and medial thalami. Our findings are in full agreement with the established neuropathological descriptions, offering a comprehensive view of atrophy patterns in AD...
  3. ncbi Global and local gray matter loss in mild cognitive impairment and Alzheimer's disease
    G B Karas
    Department of Diagnostic Radiology, Vrije Universiteit Medical Center, Amsterdam, The Netherlands
    Neuroimage 23:708-16. 2004
    ..Mild cognitive impairment (MCI) is thought to be the prodromal phase to Alzheimer's disease (AD). We analyzed patterns of gray matter (GM) loss to examine what characterizes MCI and what determines the difference with AD...

    Neuroradiology 49:967-76. 2007
    ..In this study we set out to investigate whether age at onset in patients with AD determines the pattern of atrophy on cerebral MRI scans...

    Stroke 34:1907-12. 2003
    ..The purposes of our study were to operationalize the radiological part of the NINDS-AIREN criteria and to assess the effect of this operationalization on interobserver agreement...
