Summary
The ClearPoint neuronavigation system offers real-time MRI guidance for stereotactic biopsy, with procedural times comparable to traditional frame-based methods. Efficiency is achieved after approximately four cases and requires attention to technical details.
Area of Science:
- Neurosurgery
- Medical Imaging
- Medical Device Technology
Background:
- The ClearPoint neuronavigation system provides real-time MRI guidance for stereotactic procedures.
- While offering clinical benefits, its impact on operative time requires evaluation.
Purpose of the Study:
- To retrospectively analyze procedural time for ClearPoint stereotactic biopsy.
- To compare ClearPoint procedural time with frame-based stereotactic biopsy.
Main Methods:
- Retrospective analysis of procedural times for 52 patients undergoing ClearPoint stereotactic biopsy.
- Comparison with reported times for frame-based needle biopsies.
Main Results:
- Average total procedural time for ClearPoint was 150 minutes, with 111.5 minutes for MRI acquisition and adjustments.
- This time is comparable to frame-based biopsies, with minimal time for frame mounting.
- An estimated learning curve of four cases is needed for efficiency, alongside optimized distortion correction and IT maintenance.
Conclusions:
- ClearPoint stereotactic needle biopsy is achievable within time frames similar to frame-based stereotaxis.
- Procedural efficiency necessitates a learning curve of approximately four cases.
- Vigilance in MR distortion correction and IT maintenance is crucial for optimal performance.
