A Comparison of Language Lateralization as Assessed using Functional MRI using Scanner-Generated versus Externally Calculated Statistical Parameter Maps

Aims: In the recent years, the preoperative assessment of language functions using functional MRI (fMRI) has become increasingly important in clinical practice, also for pediatric patients. Here, interpretation of results usually relies on scanner-generated statistical parameter maps. However, much more extensive processing approaches are used in the research arena. This study was aimed to directly compare these different approaches.
