[The presurgical evaluation of patients with drug-resistant epilepsy].

Comprehensive multimodal examination of patients with focal refractory epilepsies is currently a prerequisite for high-quality pre-surgical diagnostics, which aims not only to expand the indications for radical treatment of epilepsy, but also to avoid the appearance of severe postoperative deficits. High-resolution MRI plays a key role in preoperative assessment. In this review, we illustrate the modern aspects of a pre-surgical diagnostical complex in examinations of patients with focal drug-resistant epilepsy, including the possibilities of neuroimaging.
