Intraoperative magnetic resonance imaging (MRI) provides real-time guidance for neurosurgery, improving outcomes by enabling surgeons to adapt to brain shift. This advanced imaging technology offers benefits over traditional methods, though its full potential is still emerging.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Diagnostic Technology

Background:

  • Intraoperative magnetic resonance imaging (MRI) enables interactive neurosurgical procedures under magnetic resonance (MR) guidance.
  • Both low-field and high-field MRI systems are utilized in various neurosurgical interventions.

Purpose of the Study:

  • To review the applications and benefits of intraoperative MRI in neurosurgery.
  • To highlight the advantages of intraoperative MRI over frameless neuronavigational systems.
  • To discuss the impact of advanced intraoperative MR techniques on surgical decision-making.

Main Methods:

  • Implementation of low-field and high-field strength MRI for neurosurgical procedures.
  • Utilization of near real-time imaging for intraoperative guidance.

  • Application of advanced functional MR techniques (spectroscopy, fMRI, angiography, diffusion-weighted imaging).

    • Main Results:

    • Intraoperative MRI facilitates compensation for intraoperative brain shift, a key advantage over frameless systems.
    • Advanced functional MR techniques significantly influence surgical decision-making.
    • Complication rates are comparable to conventional surgery, with potential for improved outcomes due to immediate recognition.

    Conclusions:

    • Intraoperative MR-guided neurosurgery is an advancement over stereotactic techniques.
    • The technology offers potential for improved outcomes and reduced medical costs.
    • Intraoperative MRI is an evolving field with yet-to-be-determined capabilities.
