Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Neurology

Background:

  • Diffusion tensor imaging (DTI) offers detailed visualization of white matter tracts, surpassing conventional MRI in deep brain stimulation (DBS) planning.
  • Precise targeting of neural circuits is crucial for DBS efficacy, suggesting DTI can optimize surgical outcomes.

Purpose of the Study:

  • To review existing literature and evaluate the effectiveness of using DTI in DBS surgical planning.
  • To assess the impact of DTI-guided targeting on clinical outcomes in patients undergoing DBS.

Main Methods:

  • A comprehensive PubMed search was conducted using terms related to DTI and DBS.
  • Studies were included if they utilized DTI for surgical planning and reported clinical outcomes.

Main Results:

  • 35 studies evaluated DTI in DBS, focusing on movement disorders, psychiatric conditions, and pain.
  • Positive responder rates varied: 70.0% for tremor, 36.5% for OCD, 48.3% for depression, and 49.7% for chronic pain.
  • Patients with electrodes within DTI targets showed better outcomes than those without.

Conclusions:

  • DTI is a feasible tool for DBS surgical planning, offering superior information to conventional methods and potentially improving outcomes.
  • Current research is limited by small sample sizes and retrospective designs; further investigation is warranted.
  • DTI in DBS planning is underutilized, yet it holds significant potential for optimizing surgical results through this non-invasive technique.
