Surgical techniques have emerged as a viable therapeutic option in patients with drug refractory epilepsy.Pre-surgical evaluation of epilepsy requires a comprehensive, multiparametric, and multimodal approach for precise localization of the epileptogenic ps5 price new jersey focus.Various non-invasive techniques are available at the disposal of the treating physician to detect the epileptogenic focus, which include electroencephalography (EEG), video-EEG, magnetic resonance imaging (MRI), functional MRI including blood oxygen level dependent (BOLD) techniques, single photon emission tomography (SPECT), and 18 F-fluorodeoxyglucose (FDG) iphone 13 pro max price florida positron emission tomography (PET).Currently, non-invasive high-resolution MR imaging techniques play pivotal roles in the preoperative detection of the seizure focus, and represent the foundation for successful epilepsy surgery.

BOLD functional magnetic resonance imaging (fMRI) maps allow for precise localization of the eloquent cortex in relation to the seizure focus.This review article focuses on the clinical utility of BOLD (fMRI) in the pre-surgical work-up of epilepsy patients.
