title: Imaging in epilepsy.
abstract: Epilepsy is a common problem in the paediatric age group. Imaging plays a vital role in identifying the seizure focus. Cross-sectional imaging modalities like CT and MRI have had a major impact on the management of seizure disorders. MRI, because of its high contrast resolution and multiplanar capability is the ideal imaging modality but its use is restricted due to high cost. Computed tomography is cheaper and is the first, and often, the only modality used, especially in the underprivileged areas of the world. In the tropical countries inflammatory granuloma are a common cause of epilepsy and CT is adequate to detect these lesions. Other causes include congenital abnormalities, neoplastic and vascular causes.
