ObjectivesThe aim of this study was to demonstrate that eloquent cortex and epileptic-related hemodynamic changes can be safely and reliably detected using simultaneous electroencephalography (EEG)–functional magnetic resonance imaging (fMRI) recordings at ultra-high field (UHF) for clinical evaluation of patients with epilepsy.Materials and method...
Stereotactic and Functional Neurosurgery
The use of functional neuroimaging holds the promise of improving neurosurgical outcomes by providing preoperative localization of critical brain functions. The brain representation of somatosensory function can be effectively localized using magnetoencephalography (MEG) in both normal subjects and in patients with tumors, vascular malformation, an...
IntroductionBlood oxygen level-dependent functional magnetic resonance imaging (fMRI) has demonstrated its capability to provide comparable results to gold standard intracarotid sodium amobarbital (Wada) testing for preoperative determination of language hemispheric dominance. However, thus far, no consensus has been established regarding which fMR...

Our preliminary study shows that BH CVR mapping is clinically feasible and demonstrates an unexpectedly high prevalence of NVU in patients with LGG.
Magnetoencephalography (MEG) data analyzed with novel spatial filtering methods, namely event-related beamforming (ERB), have shown success in localizing hand motor areas in healthy adults and in a group of pediatric patients with peri-Rolandic tumors. The validity of this method to localize the primary motor field in a pediatric tumor case was con...
Brain Imaging and Behavior
Presurgical determination of language laterality is an important step for assessing potential risk of dysfunction resulting from brain resection within or near suspected language areas. Image-based functional MRI (fMRI) methods seek to address limitations to the clinical gold-standard technique by offering a safer, less costly, and non-invasive alt...
Audiology and Neurotology
Modern brain imaging methods now afford unprecedented opportunities for the in vivo study of central auditory system function. Positron emission tomography (PET) has been used as a functional imaging technique for more than 15 years to study the distribution of cerebral haemodynamic changes associated with auditory stimulation, in subjects with nor...
In this article we describe clinical applications of functional MRI (fMRI) at 1.0 T. All experiments were performed on a commercially available 1.0-T system (Magnetom Impact Expert, Siemens AG, Erlangen, Germany) using a blood oxygen level-dependent (BOLD)-sensitive multi-slice EPI technique (TE 66 ms, 4 mm slice thickness, 210 mm field of view, 64...
Die funktionelle Magnetresonanztomographie (fMRT) ermöglicht es, bei sprachlichen Prozessen involvierte Hirnregionen nichtinvasiv zu lokalisieren. Für die klinische Anwendung ist die Kenntnis des Einflusses der verwendeten Sprachaufgaben auf die in der fMRT dargestellte Aktivierung von entscheidender Bedeutung. In einer Probandenstudie (n=12) wurde...
