Presurgical Language Mapping With fMRI: Comparison of BOLD and fASL Techniques

Completed

• Conditions: Brain Neoplasms

• Registration Number: NCT01793714
• Lead Sponsor: Rennes University Hospital

Brief Summary

One of the aim of the neurosurgical treatment of brain tumor is to offer the maximal resection with the minimal neurological risk. The presurgical mapping of eloquent areas with functional magnetic resonance imaging (fMRI) is helpful to plan the surgery. BOLD fMRI is now the gold standard to map language areas. However, BOLD signal is diminished near the brain tumor. It is now possible to detect cortical activation with arterial spin labeling (ASL) techniques, detecting variations of perfusion during an activation paradigm (fASL), fASL could be interesting to detect eloquent areas near a brain tumor.
