Intraoperative MRI in neurosurgery offers advanced imaging but poses navigation challenges. A new software package, "3D Slicer," integrates dynamic intraoperative data for improved surgical planning and real-time adjustments, addressing brain shift.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Computer-Assisted Surgery

Background:

  • Intraoperative MRI (iMRI) has been utilized in neurosurgery since 1996.
  • Open-configuration iMRI systems have enabled over 500 open craniotomies and 100 biopsies.
  • Existing iMRI systems present challenges in terms of bulkiness and usability for surgical navigation.

Purpose of the Study:

  • To develop a software solution for dynamic integration of intraoperative imaging data into neurosurgical procedures.
  • To enhance computer-assisted navigation by providing real-time intraoperative imaging.
  • To address the limitations of current iMRI systems for surgical navigation.

Main Methods:

  • Development of a software package named "3D Slicer".
  • Integration of pre- and intraoperative imaging data visualization.

Related Experiment Videos

  • Implementation of online data acquisition for real-time updates.

    • Main Results:

    • The "3D Slicer" software has been routinely used for biopsies and open craniotomies.
    • The system demonstrates stability and reliability in clinical practice.
    • The software facilitates surgical planning and accommodates intraoperative deformations like brain shift.

    Conclusions:

    • The developed "3D Slicer" software effectively integrates dynamic intraoperative MRI data for neurosurgery.
    • This system enhances surgical navigation by providing real-time imaging and accommodating brain shift.
    • The software offers a stable and reliable solution for improving surgical outcomes in neurosurgery.
