This study introduces a 3D imaging system for intracranial surgery, enhancing preoperative planning and intraoperative localization using functional images. The system improves surgical precision and safety for brain tumor resections.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Biomedical Engineering

Background:

  • Intracranial surgery requires precise localization of critical brain structures.
  • Current methods may lack accuracy in complex anatomical cases.
  • 3D imaging offers potential for improved spatial understanding.

Observation:

  • A novel system integrates 3D functional images with MRI data for intracranial surgery.
  • Somatosensory evoked potentials (SEPs) and dipole tracing generate functional images.
  • A 3D digitizer aids in real-time intraoperative guidance.

Findings:

  • The system accurately localized central sulci preoperatively in 12 patients.
  • 3D visualization of lesions and sensorimotor cortex relationships was achieved.

  • Application in 5 brain tumor resections demonstrated minimal damage to healthy tissue.

    • Implications:

    • This technology enhances preoperative simulation and intraoperative localization accuracy.
    • It increases surgical safety and reduces damage to normal brain tissue.
    • The system holds promise for stereotactic craniotomy and complex neurosurgical procedures.
