Summary

Functional magnetic resonance imaging (fMRI) aids in presurgical planning for brain abnormalities by assessing neurological deficit risks. However, fMRI lacks clinical acceptance due to insufficient outcome studies, necessitating future research for validation.

Area of Science:

  • Neuroimaging
  • Medical technology
  • Clinical neuroscience

Background:

  • Functional magnetic resonance imaging (fMRI) visualizes brain function noninvasively.
  • fMRI relies on neurovascular coupling, primarily the blood oxygenation level dependent (BOLD) effect.
  • Presurgical fMRI is a key clinical application for patients with brain abnormalities.

Purpose of the Study:

  • To review the clinical applications of presurgical fMRI.
  • To identify the goals of presurgical fMRI: risk assessment, patient selection for mapping, and surgical guidance.
  • To define a future research roadmap for clinical acceptance of presurgical fMRI.

Main Methods:

  • Review of existing literature and clinical applications of presurgical fMRI.
  • Analysis of the role of neurovascular coupling in fMRI signal generation.

Related Experiment Videos

  • Discussion of the current limitations and future directions for presurgical fMRI.

    • Main Results:

    • Presurgical fMRI aims to assess neurological deficit risks, select patients for invasive mapping, and guide surgery.
    • Despite its potential, presurgical fMRI has not achieved widespread clinical acceptance.
    • Lack of definitive randomized trials and outcome studies hinders its validation.

    Conclusions:

    • Presurgical fMRI holds significant promise for improving surgical outcomes in patients with brain abnormalities.
    • Further research, including robust clinical trials, is essential to establish the definitive benefits and clinical validity of presurgical fMRI.
    • A clear roadmap for future research is proposed to advance presurgical fMRI towards clinical acceptance.
