Die Lokalisation von kortikalen Funktionen auf der Oberfläche der Gehirnhemisphären ist mit Hilfe von Magnetenzephalographie (MEG) und funktioneller Magnet-ResonanzTomographie (fMRT) etabliert. Dieser Ansatz ist für die Entfernung von Tumoren von großer Bedeutung, um neurologische Verschlechterungen bei der Resektion zu vermeiden. Bisher fehlte die zuverlässige Visualisierung neuronaler Bahnen ...

Augmented reality neuronavigation (ARN) systems can overlay three-dimensional anatomy and disease without the need for a two-dimensional external monitor. Accuracy is crucial their clinical applicability. We performed systematic review regarding reported accuracy of ARN compared them with conventional infrared (CIN). PubMed Embase were searched CIN systems. For ARN, type system, method patient-...

The need for novel, effective, and safe treatments for malignant glioma is obvious. Despite surgery, radiotherapy, and chemotherapy, the median survival time of patients with glioblastoma multiforme (World Health Organization Grade IV) still does not exceed 15 months. Patients with anaplastic astrocytoma (World Health Organization Grade III) have a slightly better prognosis. As a result of the ...

Introduction Biopsy and resection of brain tumors in eloquent areas remain challenging tasks because of the potential risk of postoperative neurological deficits and, consequently, a severe deterioration of life quality Biopsy and resection of brain tumors in eloquent areas remain challenging tasks because of the potential risk of postoperative neurological deficits and, consequently, a severe ...

We present the use of cortical sulci, segmented from magnetic resonance imaging, in image guided neurosurgery. Sulcal information was transferred to a surgical microscope with enhanced reality features. This assistance was used for the resection of supratentorial cavernomas (7 patients). Sulci were semi-automatically segmented from 3D MRI data sets. Sulci close to the cavernoma were selected an...

Intraoperative ultrasonography (IOUS) is a widely used noninvasive method to evaluate the morphology, vasculature, and pathologies of the brain. The advantages of IOUS include realtime depiction of neuroanatomy, accurate localization and characterization of a lesion, reduced surgical exploration and surgical time, and presumably decreased patient morbidity. IOUS is useful in the intraoperative ...
