Intracranial Electrode Visualization in Invasive Pre-surgical Evaluation for Epilepsy

Area of Science:

• Neurosurgery
• Medical Imaging
• Epilepsy Research

Background:

• Invasive intracranial electroencephalography (EEG) is crucial for identifying the epileptogenic focus in epilepsy surgery.
• Assessing the proximity of the epileptogenic zone to eloquent cortex is vital for surgical planning.
• Effective visualization of multimodal data is essential for interpreting intracranial recording and stimulation studies.

Purpose of the Study:

• To develop a software system for integrated visualization of multimodal data in epilepsy pre-surgical evaluation.
• To enhance the interpretation of intracranial EEG and cortical stimulation results.
• To improve the efficiency of epilepsy surgery planning.

Main Methods:

• Development of a software system integrating segmented brain models, post-operative MRI/CT scans, and intracranial EEG data.
• Incorporation of cortical stimulation findings into the visualization platform.
• Creation of a three-dimensional visualization environment for multimodal data fusion.

Main Results:

• The developed software successfully combines patient-specific brain anatomy, imaging data, and electrophysiological findings.
• The integrated platform provides a comprehensive view of intracranial EEG and stimulation results.
• The system facilitates a more efficient pre-surgical evaluation and surgical planning process for epilepsy.

Conclusions:

• The novel software system offers an effective solution for visualizing multimodal data in epilepsy surgery.
• This integrated approach can significantly aid neurosurgeons and neurologists in pre-surgical evaluation and planning.
• The platform has the potential to improve surgical outcomes by providing clearer insights into the epileptogenic zone and its relationship to critical brain areas.
