Zusammenfassung. Die neurochirurgische Operationsplanung stellt je nach Art des Eingriffs unterschiedliche Anforderungen an ein Planungssystem. Neben Funktionen zur Segmentierung von Tumoren und anatomischen Strukturen des Gehirns ist die Einbeziehung funktioneller Daten (EEG, fMRT, MEG) von großer Bedeutung. Die in der Planungsphase gewonnenen Ergebnisse sollten später für die intraoperative N...

Streamline representation of major fiber tract systems along with high-resolution anatomical data provides a reliable orientation for the neurosurgeon. For direct visualization of these data in the surgical field applying heads-up displays of operating microscopes, wrapping of all streamlines of interest to render an individual object representing the whole fiber bundle is mandatory. Integratio...

Removal of glioma from the dominant side of the inferior frontal gyrus (IFG) is associated with a risk of permanent language dysfunction. While intraoperative cortical and subcortical electrical stimulations can be used for functional language mapping in an effort to reduce the risk of postoperative neurological impairment, the extent of resection is limited by the functional boundaries. Recent...

BACKGROUND In dominant temporal lobe epilepsy surgery, speech, memory and visual systems are at risk. OBJECTIVE Functional magnetic resonance imaging (fMRI) and diffusion tensor imaging combined with intraoperative neuronavigation and MRI were investigated retrospectively regarding risk reductions for favorable neurological and seizure outcome. METHODS Functional imaging risk maps were gene...

Despite continuing debates around cytoreductive surgery in malignant gliomas, there is broad consensus that increased extent of tumor reduction improves overall survival. However, maximization of the extent of tumor resection is hampered by difficulty in intraoperative discrimination between normal and pathological tissue. In this context, two established methods for tumor visualization, fluore...
