Role of 1.5T Magnetic Resonance Imaging in First Line Drug Resistant Epilepsy

A seizure is defined as a paroxysmal alteration in neurologic function due to excessive electrical discharge from the central nervous system. Epilepsy is defined as a condition of recurrent seizures, and medical intractability as recurrent seizures despite optimal treatment under the direction of an experienced neurologist over a 2-3-year period. Many patients dont respond to first line antiepileptic drugs. Many imaging modalities for investigating seizures are available like neurosonogram, computerized tomography (CT scan) of brain, magnetic resonance imaging (MRI) of brain, functional MRI, positron emission tomography (PET), single photon emission computed tomography (SPECT). Of these various modalities MRI is most important modality for evaluation of structural disorders causing epilepsy. So, role of 1.5T MRI is evaluated in 102 patients with refractory epilepsy in age group 0-40 years.
