Brief summary in lay language

Brain tumors are the most common solid tumors in children, and the initial operative therapy determines not only long-term outcome, but also the rate and extent of neurological deficits. This is also true for patients with structural epilepsy. Optimal planning of this operation therefore is crucial; to this effect, advanced imaging methods are most important. Using modern approaches such as functional and diffusion magnetic resonance imaging (fMRI, dMRI), it is possible to identify brain regions involved in certain brain functions. This again allows for a more individual planning of an ensuing operation. These approaches are already in routine use for special indications in adults. However, this is not the case for children in whom these approaches are, for a number of reasons, more difficult to apply. This study is aimed at assessing the routine feasibility of such investigations in children.

Brief summary in scientific language

Brain tumors are the most common solid tumors in children, and the initial operative therapy determines not only long-term outcome, but also the rate and extent of neurological deficits. This is also true for patients with structural epilepsy, as induced by. e.g. malformations of cortical development. Optimal planning of this operation therefore is crucial; to this effect, advanced imaging methods are most important. Using modern approaches such as functional and diffusion magnetic resonance imaging (fMRI, dMRI), it is possible to identify brain regions involved in certain brain functions. This again allows for a more individual planning of an ensuing operation. These approaches are already in routine use for special indications in adults. However, applying these methods in children requires substantial expertise with regard to planning, execution, and interpretation. This combined interdisciplinary expertise is only available in select centers. This study is therefore aimed at assessing the routine feasibility of such investigations in children at a tertiary referral center.

Interventions, Observational Groups

Arm 1:
- individually-tailored, pre-operative examination using advanced MR methods - additionally, depending on endangered system, pre- and postoperative language testing, structured clinical exam or opthalmological examination will be performed

Endpoints

Primary outcome:
Feasibility of preoperatively examining the language domain using advanced MRI methods (in particular, functional MRI) in children with brain tumors or structural epilepsy. Feasibility is defined as the ratio of successfully performed, interpretable exams.
Secondary outcome:
Feasibility of preoperatively examining the sensorimotor and the visual system using advanced MRI methods (in particular, diffusions MR tractography) in children with brain tumors or structural epilepsy. Feasibility is defined as the ratio of successfully performed, interpretable exams.
