Interventional MRI enhances cancer treatment and procedures through improved visualization and speed. This review covers MRI techniques for device localization, anatomy differentiation, and temperature sensing during interventions.

Area of Science:

  • Medical Physics
  • Radiology
  • Biomedical Engineering

Context:

  • Interventional Magnetic Resonance Imaging (iMRI) has expanded beyond intrasurgical visualization.
  • It is now crucial for image-guided localization in needle-based procedures and thermal ablation of cancer.

Purpose:

  • To review the roles of MRI pulse sequences and scanning methods in interventional procedures.
  • To discuss techniques for speed improvement, device localization, anatomy/lesion differentiation, and temperature sensitivity.

Summary:

  • Examines passive visualization of MR-compatible needles, considering field strength, sequence design, and needle orientation.
  • Details methods for improved acquisition efficiency, including wavelets, locally focused imaging, singular value decomposition, and keyhole imaging.

  • Reports on thermosensitive sequences and their dependency on spin-lattice relaxation time (T1), diffusion coefficient (D), and proton chemical shift (Δ).

    • Impact:

    • Provides recommendations for both low-field and high-field iMRI scanners.
    • Highlights advancements in MRI acquisition efficiency for interventional applications.
    • Discusses the current status and influencing factors of temperature-sensitive MRI sequences for precise thermal monitoring.
