Summary
This study introduces an automated planning tool for Stereo-ElectroEncephaloGraphy (SEEG) electrode placement, significantly improving safety by maximizing distance from blood vessels and reducing planning time.
Area of Science:
- Neurosurgery
- Medical Imaging
- Computational Anatomy
Background:
- Stereo-ElectroEncephaloGraphy (SEEG) is crucial for identifying the epileptogenic zone.
- Intracranial hemorrhages are a significant complication (1%) of SEEG due to blood vessel disruption.
Purpose of the Study:
- To develop and evaluate automated planning tools for SEEG to enhance neurosurgical intervention safety.
- To optimize electrode trajectory selection and minimize risks associated with SEEG procedures.
Main Methods:
- An automated planning method was created to maximize electrode-vessel distance and avoid sulci entry points.
- Trajectory angles were optimized to minimize positioning errors.
- The automated planner was compared against manual planning using quantitative (distance, angle) and qualitative assessments.
Main Results:
- Automated trajectories demonstrated significantly greater distances from blood vessels compared to manual ones.
- Neurosurgeons preferred automated trajectories in 30% of cases and rated them acceptable in 86%.
- The automated system reduced planning time by approximately 90%.
Conclusions:
- The automated SEEG electrode planner meets clinical needs by generating safe trajectories efficiently.
- This tool enhances SEEG procedure safety and reduces neurosurgical planning time.
