A comparison of electrophysiological microrecording versus automatic MR-based segmentation to determine subthalamic nucleus boundaries
To compare the intraoperative coordinates of the STN obtained by microelectrode recording (MER) versus preoperative MR-based segmentation using Brainlab ElementsTM, highlighting the clinical significance of accurate STN targeting.
Key Findings:
Among 344 trajectories analyzed, 78.2% of electrodes were inside the STN according to both MER and ElementsTM, indicating a strong agreement that supports the reliability of both methods.
Interpretation:
Both MER and MR-based segmentation provide reliable methods for determining STN boundaries, with good concordance and minimal differences in coordinates, which is crucial for optimizing DBS outcomes.
Limitations:
Single-center study may limit generalizability; potential biases in subjective assessments of electrode placement could affect the reliability of the findings.
Conclusion:
MER and MR-based segmentation methods are both effective for STN targeting in DBS, with high concordance and minimal discrepancies in electrode placement, underscoring the need for further studies to validate these findings across diverse populations.
