Abstract: Focal cortical dysplasias are a common cause of refractory epilepsy. The findings on magnetic resonance imaging can be subtle, requiring optimal quality examination as well as extensive experience and dedica-tion from the neuroradiologist. Even under the best conditions, there are a considerable number of cases in which an injury cannot be identified. The sensitivity of its detection varies between 20 and 70%. The Morphometric Analysis Program (MAP), is a post-processing program of the magnetic resonance image whose objective is to increase the sensitivity in the detection of focal cortical dysplasia (CFD). This program works by comparing the shape, thickness and distribution of gray matter and white matter of a patient with a database of normal brains. As a result, MAP delivers 3 images that correspond to statistical volumetric maps called the union, extension and thickness map. This article discloses the operation of MAP in its different stages as well as its practical application, through some cases.
