Michiharu Morino MD, PhD, Abstract Co-Author: Nothing to Disclose

In the current ILAE classification (2010), epilepsies are not only categorized as dichotomized concepts of "focal" or "generalized" seizures.  It is recommended that epilepsy and epilepsy syndromes are described accurately according to their semiologic features. Therefore, multimodal neuroimaging plays a pivotal role in the comprehensive evaluation of epilepsy patients. Advances enabling higher spatial resolution, tissue contrast, multiplanar imaging capability, 3D-visualization of neuronal pathways, and fusion imaging can assist with microstructual lesion detection and determination of surgical candidates. Ragiologists contribute to patient care through both acknowledging the role of imaging and multidisciplinary communication, with consensus. 

An algorithmic approach to the evaluation and management of epilepsy patients. Illustrations of epileptogenic pathologies and syndromes: (1) hippocampal sclerosis, (2) malformations of cortical development, (3) neoplasms, (4) vascular lesions, (5) ion-channel disorders, (6) metabolic disorders, etc. Systematic imaging approach with STIR, 3D-T1WI, DTI, fMRI, FDG-PET, 123I-iomazenil and 99mTc-ECD SPECT, and magnetic source (MS) imaging. Post-processing techniques; pros/cons and diagnostic capabilities of imaging. Contributions of imaging to surgery.
