Correlation of preoperative fMRI and neuronavigation guided intraoperative neurophysiological monitoring (IOM)

Surgical treatment of space occupying lesions in sensorimotor cortex and in vicinity of them bears either the risk of postoperative neurological deficit or incomplete tumor resection. Preoperative implementation of functional magnetic resonance imaging (fMRI) into neuronavigation systems seems to diminish the risk of postoperative neurological deficit and enables most possible tumor resection. Localisation of motor cortex via intraoperative neurophysiological monitoring (IOM) also seems to lead to best postoperative functional results. The intention of this study is to compare the topographic orientation of the…
