Functional MRI (fMRI) is crucial for neurosurgical planning. It helps assess tumor resectability, map brain function like language and memory, and localize epilepsy foci, improving surgical outcomes.

Area of Science:

  • Neurosurgery
  • Radiology
  • Neuroimaging

Background:

  • Functional MRI (fMRI) is increasingly utilized in preoperative planning for neurosurgical patients.
  • Its role continues to expand, offering significant benefits in patient management.

Purpose of the Study:

  • To describe current indications for fMRI in preoperative neurosurgical planning.
  • To highlight the expanding role of fMRI in optimizing surgical strategies.

Main Methods:

  • Review of current clinical applications of fMRI in neurosurgery.
  • Discussion of three main patient categories benefiting from preoperative fMRI.
  • Mention of advances in multimodality imaging for intraoperative localization.

Main Results:

Related Experiment Videos

  • fMRI aids in assessing resectability and reducing deficits for lesions near eloquent cortex.
  • It is used for preoperative localization of language dominance and memory function.
  • Electroencephalographic-correlated fMRI (EEG-fMRI) assists in localizing abnormal brain function, particularly in epilepsy surgery.

Conclusions:

  • Preoperative fMRI, combined with intraoperative imaging, can reduce neurological deficits and improve resection completeness.
  • EEG-fMRI offers a valuable tool for localizing epileptogenic foci, aiding epilepsy surgery planning.
