Ressonância magnética funcional, princípios, metodologiaResumo
Atualmente há grande interesse em métodos funcionais não invasivos que poderiam localizar a zona epileptogênica e sua relação com as diversas áreas funcionais corticais. Entre essas novas metodologias, a ressonância magnética funcional é provavelmente um instrumento com potencial para uso na prática clínica. Nós revisamos seus princípios e metodologia.
