PURPOSE The aim of this study was to present a tractography algorithm using a two-tensor unscented Kalman filter (UKF) to improve the modeling of the corticospinal tract (CST) by tracking through regions of peritumoral edema and crossing fibers. METHODS Ten patients with brain tumors in the vicinity of motor cortex and evidence of significant peritumoral(More)
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 pose a challenge to conventional tractography using the standard diffusion tensor model. The aim of this study was to present a novel(More)
BACKGROUND Intraoperative magnetic resonance imaging (IoMRI) was devised to overcome brain shifts during craniotomies. Yet, the acceptance of IoMRI is limited. OBJECTIVE To evaluate impact of IoMRI on intracranial glioma resection outcome including overall patient survival. METHODS A retrospective review of records was performed on a cohort of 164(More)
