PIC 1 Brain imaging: MRI techniques |
|
|
PIC 2 Interictal and Ictal SPECT scans are digitally merged and fused with MRI |
|
|
PIC 3 magnetoencephalography (magnetic source imaging) is used to assist in the three-dimensional localization of the epileptogenic focus |
|
|
PIC 4 Depth electrodes placed directly into brain structures |
|
|
PIC 5a Subdural strip or grid electrodes placed over the cortical surface of the brain |
|
|
PIC 5b Subdural strip or grid electrodes placed over the cortical surface of the brain |
|
|
PIC 6 MRI-directed stereotactic implantation of depth electrodes into specific brain structures |
|
|
DRAW 1 Anterior temporal lobectomy - removal of the anterior temporal lobe including the medial temporal structures |
|
|
PIC 7 Extratemporal resection - removal of epileptogenic cerebral cortex outside the anterior temporal lobe |
|
|
PIC 8a Functional hemispherectomy - removal of the majority of one cerebral hemisphere and functional disconnection of the remainder of the hemisphere |
|
|
PIC 8b Functional hemispherectomy - removal of the majority of one cerebral hemisphere and functional disconnection of the remainder of the hemisphere |
|
|
DRAW 2a Hemispherotomy - disconnecting the damaged, epileptogenic hemisphere rather than removing tissue |
|
|
DRAW 2b Hemispherotomy - disconnecting the damaged, epileptogenic hemisphere rather than removing tissue |
|
|
PIC 9 Corpus Callosotomy - sectioning of the corpus callosum to disconnect the two hemispheres and prevent the spread of seizures from one hemisphere to the other |
