Summary
Neurosurgeons can use 3D-Slicer to build brainstem fiber bundles for preoperative planning. This improves understanding of lesion-to-fiber relationships, enabling safer tumor resection and nerve function preservation.
Area of Science:
- Neurosurgery
- Medical Imaging
- Computational Anatomy
Background:
- Preoperative planning for brainstem lesions is challenging due to complex fiber tract anatomy.
- Accurate visualization of the relationship between lesions and critical white matter tracts is crucial for surgical success.
Purpose of the Study:
- To evaluate the method and clinical value of neurosurgeons self-constructing brainstem fiber bundles using 3D-Slicer software for preoperative planning.
- To assess the impact of this technique on surgical approach development and patient outcomes.
Main Methods:
- Collected DCIOM imaging data from 31 patients with brainstem lesions.
- Utilized 3D-Slicer software for independent construction of fiber bundles by neurosurgeons.
- Generated 2D Fraction Anisotropy (FA) maps, Directionally Encoded Color (DEC) maps, and 3D fiber tracing maps.
Main Results:
- Successful reconstruction of brainstem fiber bundles in all 31 cases.
- Surgical plans were developed using self-constructed 3D virtual images, leading to successful tumor resection with minimal fiber bundle damage.
- Postoperative follow-up showed mild or no symptoms of new brainstem fiber bundle injury at 3 and 6 months.
Conclusions:
- Self-construction of brainstem fiber bundles by neurosurgeons enhances understanding of 3D pathological anatomy.
- This technique facilitates more reasonable surgical plan formulation, optimal approach selection, and identification of safe surgical corridors.
- Improved visualization leads to increased confidence in avoiding damage to fiber bundles, promoting maximal tumor resection and nerve function preservation.
