Investigacao do uso da analise de textura de imagens de ressonancia magnetica como ferramenta de auxilio na caracterizacao das epilepsias refratarias

In refractory epilepsies, therapies that use two or more antiepileptic drugs do not result in the control of the crises. The patients can present diffuse or focal cortical dysplasia (FCDs) and/or hippocampus atrophic changes that, in some cases, are not detectable by a simple visual analysis of the magnetic resonace (MR) images. In this context, the objective of this study was to assess the MR images texture in regions of interest (ROIs) placed in the hippocampi, limbic association cortex and prefrontal cortex of 20 patients with refractory epilepsy, and compare them with the same areas of a g...
