The surgical treatment of patients with complex epilepsies is
changing more and more from open, invasive surgery towards minimally
invasive, image guided treatment. Multi-modal brain imaging procedures
are developed to delineate preoperatively the region of the brain which is
responsible for the epilepsy of a patient and delimit the functional areas
relative to this region. The ultimate aim is to provide the neurosurgeon
with a clear and intuitive image of the targeted epileptogenic region in
order to render the patient seizure free, while avoiding damage to elo-
quent cortex.
A software product (SP) is developed for multi-modality map-
ping of the analysis results of non-invasive and invasive epilepsy record-
ings and visualization of these results against brain anatomy. The SP
contains several pre-programmed sequences for creating the most com-
monly used multi-modality brain images that can be used to delineate the
epileptic tissue versus functional areas, like visualization of inverse solu-
tions of high density EEG and MEG, EEG informed functional MRI
(fMRI) visualizations and functional Near-Infrared Spectroscopy
(fNIRS) projections.
The SP is optimized for intuitive and clinical usage to interac-
tively explore the different modalities in relation to the available anatom-
ical and structural MRI data. The distinct modalities can be combined by
3D-fusion of the images and visualized in 2D- and 3D-MRI viewports
against the implanted depth electrodes and the brain mapping results of
the invasive EEG recordings.
Multi-modal functional and structural brain imaging
applied on data of the individual patient can be used for guiding surgical
resections with minimal disruption of brain anatomy, while rendering a
patient seizure free.
