Brain Imaging

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Area of Science:

Neurosurgery
Medical Imaging

Background:

Functional magnetic resonance imaging (fMRI) is vital for neurosurgical procedures involving the eloquent cortex.
Despite advancements, clinical fMRI faces limitations impacting its application.

Purpose of the Study:

To review the clinical applications of fMRI in neurosurgery.
To identify and discuss the limitations of clinical fMRI and propose potential solutions.
To compare fMRI with alternative brain mapping modalities.

Main Methods:

Review of existing literature on clinical fMRI in neurosurgery.
Analysis of factors influencing fMRI limitations, including physiological effects and study design.
Comparison of fMRI with other neuroimaging techniques for brain mapping.

Main Results:

Clinical fMRI offers valuable preoperative and intraoperative guidance for tumor resection.
Key limitations stem from fMRI's foundational principles, disease-related physiological changes, and study design.
fMRI performance is influenced by the distinction between clinical and research settings.

Conclusions:

Addressing fMRI limitations is crucial for optimizing its clinical utility in neurosurgery.
Alternative or adjunct brain mapping modalities should be considered.
Further validation and refinement of intraoperative fMRI are necessary for enhanced patient care.
