Blood 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 fMRI paradigms are the most effective for the determination of hemispheric language lateralization in specific categories of patients and specific regions of interest (ROIs). ⋯ SWG and R are sufficient for the determination of lateralization in expressive language areas, whereas new semantic or receptive paradigms need to be designed for an improved assessment of lateralization in receptive language areas.

The objective of this study was to analyze the place for the balloon remodeling and stenting in the endovascular treatment of intracranial aneurysms as well as the impact of their use on the failure and complications rates. Analysis was conducted in a recent 3-year period (2008-2010) in a single center. ⋯ In the endovascular management of intracranial aneurysms, the large use of the remodeling technique combined with stenting in selected cases enables a low rate of treatment failures without increasing the rate of complications.
