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.
