Area of Science:

  • Pain Management
  • Interventional Radiology
  • Medical Imaging

Background:

  • Celiac plexus block is a palliative treatment for severe upper abdominal pain from pancreatitis or pancreatic tumors.
  • Guidance methods include bony landmarks, fluoroscopy, ultrasound (US), and computed tomography (CT).
  • Soft tissue visualization methods like CT and magnetic resonance (MR) imaging are preferred to minimize complications.

Purpose of the Study:

  • To describe the technique and outcomes of celiac plexus blocks performed using an open MR scanner.
  • To evaluate the safety and efficacy of MR-guided celiac plexus blocks.

Main Methods:

  • Celiac plexus blocks were performed in an open MR scanner with an optical tracking system for needle guidance.
  • Near real-time image acquisition was utilized.

  • Eight patients with severe chronic abdominal pain underwent 14 procedures.

    • Main Results:

    • MR guidance facilitated accurate needle placement in all cases.
    • Effective pain relief (good or total) was achieved in 57% of the blocks.
    • Moderate pain relief was observed in 36% of the blocks.

    Conclusions:

    • Celiac plexus block can be safely and effectively performed in an open MR scanner.
    • MR imaging provides superior soft tissue visualization and needle monitoring, avoiding ionizing radiation.
    • This technique offers a viable alternative for managing chronic abdominal pain.
