Multimodality localization of epileptic foci
This paper presents a multimodality approach for the localization of epileptic foci using PET, MRI and EEG combined without the need of external markers. Mutual Information algorithm is used for MRI-PET registration. Dipole coordinates (provided by BESA software) are projected onto the MRI using a specifically developed algorithm. The four anatomical references used for electrode positioning (n...
متن کاملPositron Emission Tomography in Presurgical Localization of Epileptic Foci
Ictal intracranial EEG correlates of cortical FDG and FMZ PET abnormalities in patients with neocortical epilepsy…………………. 21 4.1.1. FMZ PET is more sensitive than FDG PET in detection of seizure onset defined by intracranial EEG monitoring……21 4.1.2. Seizure onset occurs most often at the border of cortex with glucose hypometabolism……………………………….. 21 4.2. Electroclinical correlates of FDG and FM...
متن کاملPositron emission tomography in presurgical localization of epileptic foci.
The success of cortical resection for intractable epilepsy of neocortical origin is highly dependent on the accurate presurgical delineation of the regions responsible for generating seizures. In addition to EEG and structural imaging studies, functional neuroimaging such as positron emission tomography (PET) can assist lateralization and localization of epileptogenic cortical areas. In the pre...
متن کاملMagnetoencephalography in Preoperative Epileptic Foci Localization: Enlightenment from Cognitive Studies
Over 30% epileptic patients are refractory to medication, who are amenable to neurosurgical treatment. Non-invasive brain imaging technologies including video-electroencephalogram (EEG), magnetic resonance imaging (MRI), and magnetoencephalography (MEG) are widely used in presurgical assessment of epileptic patients. This review mainly discussed the current development of clinical MEG imaging a...
متن کاملLocalization of epileptic foci in Children with childhood absence epilepsy by magnetoencephalography combined with synthetic aperture magnetometry☆
This present study was aimed to investigate the localizable diagnostic value of magnetoencephalography (MEG) combined with synthetic aperture magnetometry (SAM) in childhood absence epilepsy (CAE). Thirteen CAE patients underwent MEG detection at resting state and after hyperventilation, and then the epileptic foci were located by SAM. In the thirteen CAE patients, epileptic foci were found in ...
