Preoperative Functional MR Imaging in Patients with BrainTumors

Our results indicate that fMRI and DCS are complementary methods. FMRI is able to navigate DCS and allows to consider lateralization of language function which is important in surgical planning. We used “semantic decision task” which allows us to control patient`s responses. This paradigm is potentially able to substitute for the battery of tasks which are used in combination in order to increase sensitivity of preoperative language mapping.
