Abstract
Functional magnetic resonance imaging (fMRI) is a useful strategy for presurgical planning and operative guidance in neurosurgery. This chapter will review what fMRI measures, applications of presurgical fMRI for localizing individual-specific functional anatomy, and methodological issues that should be considered when interpreting functional neuroimaging data in individual cases. The focus will be on planning for tissue resection in epilepsy and tumor surgery. The current applications and potential uses of functional neuroimaging for guiding deep-brain stimulation implantation in movement disorders, chronic pain and psychiatric disorders will also be described.
In the common "task-based" fMRI approach, brain activity is measured while a patient performs tasks that involve sensorimotor, language and memory functions to localize eloquent cortex. Recent developments suggest that "resting-state" fMRI, in which spontaneous brain activity is measured while a patient is in a task-free state, is a feasible, and potentially more useful, alternative for presurgical mapping of a broader range of functional regions. In both approaches, due to low signal-to-noise, data analysis issues, and the correlational nature of the approach, fMRI data in individual cases must be interpreted with caution. Ongoing research efforts are leading to increased sensitivity and specificity of functional neuroimaging, which may enable more effective and broader applications for personalized functional neurosurgery in the future.
