Magnetic resonance imaging (MRI) navigation enhances minimally invasive procedures. Open MRI scanners offer workflow benefits, while closed-bore systems present navigation challenges but leverage advanced imaging capabilities.

Area of Science:

  • Medical imaging
  • Minimally invasive interventions
  • Medical device technology

Background:

  • Magnetic resonance imaging (MRI) techniques are advancing, enabling sophisticated guidance for minimally invasive procedures.
  • Navigation concepts for MRI-guided interventions vary based on MR scanner design and the clinical environment.
  • Open MRI scanners facilitate easier workflow and reduce the need for spatial coordinate mapping (coregistration).

Purpose of the Study:

  • To provide an updated overview of MRI-based navigation techniques for medical interventions.
  • To discuss the clinical experiences and limitations of selected MRI navigation systems.

Main Methods:

  • Review of existing MRI-based navigation concepts and technologies.
  • Analysis of advantages and limitations related to open and closed-bore MRI scanner designs.

  • Discussion of emerging technologies like multimodal overlays, augmented reality, and robotic assistance.

    • Main Results:

    • Open MRI scanners offer improved workflow and reduced coregistration requirements.
    • Closed-bore MRI systems, despite technical challenges, are advancing due to imaging capabilities and economic value.
    • Advanced navigation concepts are still in early development but show potential for future intraoperative use.

    Conclusions:

    • MRI-based navigation is a developing field with diverse approaches.
    • Scanner design significantly impacts the feasibility and workflow of MRI-guided interventions.
    • Future advancements in technology may further enhance the utility of intraoperative MRI navigation.
