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 Stimulation (TMS).

Summary

This study introduces fusion imaging for programming deep brain stimulation in advanced Parkinson disease (PD). This method efficiently improved motor symptoms and reduced medication needs after subthalamic nucleus (STN) DBS.

Area of Science:

  • Neurosurgery
  • Neurology
  • Medical Imaging

Background:

  • Advanced Parkinson disease (PD) presents significant motor challenges.
  • Subthalamic nucleus deep brain stimulation (STN DBS) is a therapeutic option for advanced PD.
  • Optimizing STN DBS programming is crucial for effective patient management.

Purpose of the Study:

  • To propose and evaluate fusion image-based programming for STN DBS in advanced PD patients.
  • To assess the efficacy and efficiency of this novel programming approach.

Main Methods:

  • 38 advanced PD patients received STN DBS.
  • Electrode and contact localization used fused preoperative MRI and postoperative CT images.
  • Postoperative programming guided by fused image data.
  • Patients assessed using UPDRS, Hoehn and Yahr, SEADL, LEDD, SF-36, and neuropsychological tests.

Main Results:

  • Significant improvement in motor symptoms (tremor, rigidity) post-STN DBS.
  • Approximately 55% improvement in off-medication UPDRS III scores at 3 and 6 months.
  • Marked reduction in dyskinesia (74% at 3 months, 95% at 6 months).
  • Levodopa equivalent daily dose (LEDD) reduced by 50% within 1 month post-surgery.

Conclusions:

  • Fusion image-based programming for STN DBS is quick, easy, and efficient.
  • This method effectively adjusts STN DBS for advanced PD patients.
  • The approach leads to significant clinical improvements and reduced medication.
