Intraoperative MRI improves neurosurgical accuracy by compensating for brain shift, offering real-time imaging and navigation. This enhances lesion targeting and resection assessment compared to traditional preoperative methods.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Surgical Navigation

Background:

  • Neuronavigation is standard in neurosurgery for precise localization.
  • Preoperative imaging limits accuracy due to intraoperative brain shift.
  • Intraoperative MRI (iMRI) offers real-time imaging and navigation to overcome these limitations.

Purpose of the Study:

  • To review the authors' experience with two intraoperative MRI systems.
  • To highlight the benefits of iMRI in neurosurgical procedures.
  • To compare different iMRI system approaches.

Main Methods:

  • Review of neurosurgical procedures utilizing intraoperative MRI.
  • Experience with the GE Signa SP System.
  • Experience with the Odin PoleStar System.

Main Results:

  • Intraoperative MRI provides updated images, compensating for brain shift.
  • Enables integrated navigation and assessment of resection extent.
  • Systems vary in complexity, usability, and cost.

Conclusions:

  • Intraoperative MRI significantly enhances neurosurgical accuracy and safety.
  • Real-time imaging and navigation are crucial for complex procedures.
  • The choice of iMRI system depends on specific clinical needs and resources.
