Global fiber reconstruction aims at providing a consistent view of the fiber architecture in the whole volume of cerebral white matter on the basis of diffusion-sensitized magnetic resonance imaging. A new realization of this principle is presented. The method utilizes data acquired with high angular resolution diffusion imaging (HARDI), a measurement(More)
BACKGROUND In contrast to the abundance of seizure outcome reports in epilepsy surgery for glioneuronal tumors in childhood and adolescence, there is a dearth of information regarding cognitive outcomes. OBJECTIVE To investigate the seizure and cognitive outcome of children and adolescents that underwent resective surgery for glioneuronal tumor-associated(More)
Decompressive craniectomy (DC) is a controversially discussed neurosurgical procedure to reduce elevated intracranial pressure after severe traumatic brain injury (TBI). In contrast to adults, several studies could show a benefit for the pediatric population, but still DC is considered as an emergency procedure only. The aim of our study was to identify(More)
We present a 49-year-old male who suffered a cerebellar infarction due to a vertebral artery dissection. The patient had taken sildenafil daily for at least 2 years for sexual enhancement. There was no sexual intercourse or traumatic event prior to symptom onset. Sildenafil intake has been associated with aortic dissection and, in the light of this report,(More)
PURPOSE Global tracking (GT) is a recently published fibre tractography (FT) method that takes simultaneously all fibres into account during their reconstruction. The purpose of this study was to compare this new method with fibre assignment by continuous tracking (FACT) and probabilistic tractography (PT) for the detection of the corticospinal tract (CST)(More)
