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...

Background:

Deep brain stimulation (DBS) efficacy relies on modulating brain circuitry, but current planning lacks white matter visualization.
Diffusion MRI tractography (DT) offers non-invasive visualization of brain structural connectivity.
DT is proposed to enhance DBS targeting for conditions like Parkinson's disease and essential tremor.

Purpose of the Study:

To review the technical aspects, methodologies, and preliminary clinical data of using DT in DBS surgery.
To focus on generalizable methods applicable to diverse DBS targets, rather than specific disease applications.

Main Methods:

Review of technical details and proposed methods for Diffusion MRI tractography (DT) in DBS.
Analysis of initial clinical data supporting DT-guided DBS.
Focus on standardization and anatomical validation challenges.

Main Results:

DT enables visualization of white matter pathways crucial for DBS targeting.
DT-guided DBS holds potential for precise targeting in established and novel therapeutic applications.
Concerns regarding DT standardization and validation for surgical use are highlighted.

Conclusions:

Diffusion MRI tractography presents a promising tool for enhancing the precision of deep brain stimulation.
Further standardization and validation are necessary for the reliable integration of DT into stereotactic neurosurgery.
DT-guided DBS may expand therapeutic options for a range of neurological and psychiatric disorders.
