    • Fiber clustering versus the parcellation-based connectome 

      O'Donnell, Lauren Jean; Golby, Alexandra Jacqueline; Westin, Carl-Fredrik (Elsevier BV, 2013)
      We compare two strategies for modeling the connections of the brain's white matter: fiber clustering and the parcellation-based connectome. Both methods analyze diffusion magnetic resonance imaging fiber tractography to ...
    • fMRI-DTI modeling via landmark distance atlases for prediction and detection of fiber tracts 

      O'Donnell, Lauren Jean; Rigolo, Laura; Norton, Isaiah; Wells, William Mercer; Westin, Carl-Fredrik; Golby, Alexandra Jacqueline (Elsevier BV, 2012)
      The overall goal of this research is the design of statistical atlas models that can be created from normal subjects, but may generalize to be applicable to abnormal brains. We present a new style of joint modeling of fMRI, ...
    • A Method for Clustering White Matter Fiber Tracts 

      O'Donnell, Lauren Jean; Kubicki, Marek R.; Shenton, Martha Elizabeth; Dreusicke, M.H.; Grimson, W.E.L.; Westin, Carl-Fredrik (American Society of Neuroradiology, 2006)
      BACKGROUND/PURPOSE: Despite its potential for visualizing white matter fiber tracts in vivo, diffusion tensor tractography has found only limited applications in clinical research in which specific anatomic connections ...
    • Reconstruction of the arcuate fasciculus for surgical planning in the setting of peritumoral edema using two-tensor unscented Kalman filter tractography 

      Chen, Zhenrui; Tie, Yanmei; Olubiyi, Olutayo; Rigolo, Laura; Mehrtash, Alireza; Norton, Isaiah; Pasternak, Ofer; Rathi, Yogesh; Golby, Alexandra J.; O'Donnell, Lauren J. (Elsevier, 2015)
      Background: Diffusion imaging tractography is increasingly used to trace critical fiber tracts in brain tumor patients to reduce the risk of post-operative neurological deficit. However, the effects of peritumoral edema ...
    • Visual Pathway Study Using In Vivo Diffusion Tensor Imaging Tractography to Complement Classic Anatomy 

      Wu, Wentao; Rigolo, Laura; O'Donnell, Lauren Jean; Norton, Isaiah; Shriver, Sargent; Golby, Alexandra Jacqueline (Oxford University Press (OUP), 2012)
      BACKGROUND: Knowledge of the individual course of the optic radiations (ORs) is important to avoid postoperative visual deficits. Cadaveric studies of the visual pathways are limited because it has not been possible to ...
