ABSTRACT BACKGROUND AND PURPOSE Functional magnetic resonance imaging
(fMRI) is becoming widely recognized as a key component of preoperative neurosurgical …

Introduction: Functional magnetic resonance imaging (fMRI) is a neuroradiological
technique for the localisation of cortical function. FMRI made its debut in cognitive …

The surgical removal of brain tumours in so-called eloquent regions is frequently associated
with a high risk of causing disabling postoperative deficits. Among the preoperative …

Functional magnetic resonance imaging (fMRI) using the blood-oxygenation level
dependent (BOLD) contrast measures local changes in the concentration of paramagnetic …

Introduction The resection of left-sided perisylvian brain lesions harbors the risk of
postoperative language impairment. Therefore the individual patient's language distribution …

Objectives To analyse the long-term feasibility and limitations of presurgical fMRI in a cohort
of tumour and epilepsy patients with different MR-scanners at 1.5 and 3.0 T. Methods Four …

Resting state fMRI (rs-fMRI) has recently been considered as a possible complement or
alternative to task-based fMRI (tb-fMRI) for presurgical mapping. However, evidence of its …

Pre-surgical mapping of sensorimotor and language functions is crucial to reduce
neurological deficits in epilepsy and tumor resection surgery. As non-invasive mapping, both …

Background The resection of left-sided perisylvian brain lesions harbours the risk of
postoperative language impairment. Therefore the individual patient's language distribution …

Presurgical mapping using functional neuroimaging techniques—and particularly fMRI—is
now commonly used in clinical practice and not just for research applications. Presurgical …
