Summary
Cortical sulci from MRI scans enhance neurosurgery by guiding surgeons. This image-guided approach improves tumor resection and patient outcomes in complex brain surgeries.
Area of Science:
- Neurosurgery
- Medical Imaging
- Neuroanatomy
Context:
- Image-guided neurosurgery is crucial for precise tumor resection.
- Supratentorial cavernomas present unique surgical challenges.
- Integrating anatomical landmarks into surgical navigation systems is an ongoing area of research.
Purpose:
- To evaluate the utility of semi-automatically segmented cortical sulci in image-guided neurosurgery.
- To assess the effectiveness of superimposing sulcal information onto a surgical microscope for enhanced reality visualization.
- To determine if sulcal trajectories can serve as indirect guides for accessing brain lesions.
Summary:
- Cortical sulci were segmented from 3D MRI data and transferred to a neuronavigation system.
- This sulcal information was superimposed into the ocular of a surgical microscope with enhanced reality features.
- The system was applied in the resection of supratentorial cavernomas in 7 patients, with sulci aiding anatomical recognition and trajectory planning.
Impact:
- Cortical sulci provide valuable anatomical context during neurosurgical procedures.
- Superimposed sulci assist in optimizing skin incision parameters and guiding surgical access to deep-seated lesions.
- This technique offers a novel method for improving spatial orientation and precision in neurosurgery.
