Update on Adult Epilepsy: What Neuroradiologists Should Know
Neuroimaging is an important component of diagnosis and presurgical planning for localization-related epilepsy. The evaluation and treatment of medication-refractory epilepsy are changing as clinicians move toward less invasive and more selective and adaptive approaches. This article
reviews concepts and terms, including the International League Against Epilepsy 2017 revised classification of seizures; presents common lesions and approaches to finding them; and provides updates in advanced structural and functional imaging. Finally, we summarize current less invasive therapies
for focal epilepsy.
Learning Objectives:
Learning Objectives:
1) To summarize epilepsy terms, concepts, and statistics
2) To identify common epileptogenic lesions and structural imaging pitfalls
3) To become familiar with imaging protocols and techniques including complementary functional imaging
4) To understand new trends and devices in surgical evaluation and therapy
