Three-dimensional visualization of subdural electrodes for presurgical planning.
BACKGROUND Accurate localization and visualization of subdural electrodes implanted for intracranial electroencephalography in cases of medically refractory epilepsy remains a challenging clinical problem. OBJECTIVE We introduce a technique for creating accurate 3-dimensional (3D) brain models with electrode overlays, ideal for resective surgical planning. METHODS Our procedure uses postimp...
متن کاملProblem of signal contamination in interhemispheric dual-sided subdural electrodes.
Dual-sided subdural electrodes are used in the localization and lateralization of seizure-onset zones when the area of interest is within the interhemispheric fissure. We designed the current study to test the validity of the assumption that each side of the dual-sided electrodes records from the hemisphere it faces. We recorded with dual-sided strip and grid electrodes implanted in the occipit...
متن کاملSubacute Subdural Hematoma in a Patient with Bilateral DBS Electrodes
Subdural hematomas (SDH) in patients with implanted deep brain stimulating (DBS) electrodes are rare. Only a handful of cases have been reported in the literature. No clear management guidelines exist regarding the management of the hematoma and the existing electrodes. We describe a 68-year-old female with bilateral DBS electrodes, who presented with acute, severe hemiparesis due to a large su...
متن کامل3D source localization derived from subdural strip and grid electrodes: a simulation study.
OBJECTIVE Little experience exists in the application of source reconstruction methods to recordings from subdural strip and grid electrodes. This study addressed the question, whether reliable and accurate 3D source localization is possible from the Electrocorticogram (ECoG). METHODS The accuracy of source reconstruction was investigated by simulations and a case study. Simulated sources wer...
متن کاملAutomatic and Precise Localization and Cortical Labeling of Subdural and Depth Intracranial Electrodes
Object: Subdural or deep intracerebral electrodes are essential in order to precisely localize epileptic zone in patients with medically intractable epilepsy. Precise localization of the implanted electrodes is critical to clinical diagnosing and treatment as well as for scientific studies. In this study, we sought to automatically and precisely extract intracranial electrodes using pre-operati...
