Area of Science:

  • Medical Imaging
  • Interventional Radiology
  • Biomedical Engineering

Background:

  • Intravascular interventional procedures require precise guidance for optimal outcomes.
  • Current guidance techniques like fluoroscopy have limitations, including radiation exposure.
  • Magnetic resonance (MR) imaging offers high soft-tissue contrast and lacks ionizing radiation.

Purpose of the Study:

  • To evaluate the practicability and localizing precision of a novel MR imaging technique for real-time catheter tracking.
  • To compare the accuracy of MR catheter tracking with traditional fluoroscopy.
  • To assess the feasibility of MR-guided catheter placement in vivo.

Main Methods:

  • Development and assessment of catheter-tip radiofrequency (RF) coils and specialized feed cables.

  • In vivo evaluation in a swine model using a prototype 5-French MR tracking catheter.

    • Main Results:

    • A fully shielded coaxial cable was essential for accurate RF coil localization.
    • MR and fluoroscopy measurements of catheter tip position showed strong correlation (r > .98) with a 6-mm confidence interval.
    • Real-time MR tracking of catheter tips was successful both in vitro and in vivo, with accurate placement in swine vasculature.

    Conclusions:

    • MR imaging enables robust in vivo tracking of catheters.
    • Catheters equipped with miniature RF coils can be accurately placed using MR guidance.
    • This technique holds promise for improving the safety and precision of interventional procedures.
