  • MRI offers significant advantages, including the ability to perform interventions under real-time MR control without using X-rays.
  • Open-configuration MRI systems facilitate vertical patient access during procedures, and combining MRI with laparoscopy allows simultaneous observation of organ surfaces and parenchymal structures.

    • Impact:

    • MRI's high temperature sensitivity makes it suitable for guiding interstitial laser therapy or cryosurgical interventions.
    • The integration of MRI with surgical techniques like laparoscopy enhances diagnostic and therapeutic capabilities.
    • MRI provides a non-invasive, real-time imaging solution for complex interventional procedures.
