This study shows intraarterial contrast administration is feasible for MR-guided intravascular interventions. Selective contrast injection aids navigation, assesses flow, and evaluates treatment with reduced contrast dose.

Area of Science:

  • Medical Imaging
  • Interventional Radiology
  • Magnetic Resonance Imaging (MRI)

Background:

  • MR-guided intravascular interventions require precise catheter navigation and real-time treatment evaluation.
  • Traditional intravenous contrast-enhanced MR angiography (CE-MRA) may use high contrast doses and have limitations in 2D imaging.

Purpose of the Study:

  • To investigate the feasibility of intraarterial contrast administration for MR-guided intravascular interventions.
  • To explore its utility in navigation, flow assessment, and treatment evaluation.
  • To develop an optimized injection protocol for selective contrast delivery.

Main Methods:

  • Developed an injection protocol considering MRI sequence parameters and vessel flow rate.
  • Conducted phantom and animal experiments to evaluate intraarterial contrast administration.

  • Synchronized selective contrast injection with 2D and 3D CE-MRA acquisitions.

    • Main Results:

    • Tracking intraarterial contrast boluses effectively verified catheter tip position and assessed flow conditions.
    • Selective contrast administration significantly reduced the required dose compared to intravenous CE-MRA.
    • Prevented vessel overlap in 2D acquisitions and maintained high contrast concentration in 3D CE-MRA.

    Conclusions:

    • Intraarterial contrast administration is a feasible and effective technique for MR-guided intravascular interventions.
    • It facilitates catheter navigation, provides crucial flow information, and allows repeated treatment progress evaluation.
    • Selective contrast delivery offers advantages in dose reduction and image quality over conventional intravenous methods.
