“Multimodal image processing in the presurgical evaluation of epilepsy” | |
sumário |
Surgical resection of the epileptogenic
zone can be an effective treatment for some patients with medically
intractable focal epilepsies. The process of presurgical evaluation
aims at the exact localization of the epileptogenic zone and its
relation to eloquent cortex. Usually the whole range of available imaging methods like computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET) and single photon emission computed tomography (SPECT) is utilized. Each imaging modality will reveal different structural or physiological characteristics of the brain and thus can contribute complementary information, reflecting different aspects of the complex pathopysiologic network of epileptogenicity. However, the integrated threedimensional visualization of several neuroimaging and electrophysiological examinations is of additional value for anatomically detailled planning of resective surgery. The application of image registration and 3D volume rendering is described for improvements within single modalities as well as for multimodal visualization. |
