Summary

Computed tomography fluoroscopy (CTF) offers real-time guidance for non-vascular interventions, significantly reducing procedure times and improving access to deep organ lesions. Initial experiences show CTF enhances efficiency and safety, meeting radiological protection guidelines.

Area of Science:

  • Medical Imaging
  • Interventional Radiology

Background:

  • Computed Tomography Fluoroscopy (CTF) is an emerging technology enabling real-time imaging guidance.
  • Validation of its efficacy is crucial before widespread adoption in clinical practice.

Purpose of the Study:

  • To review initial experiences with CTF for non-vascular interventions.
  • To evaluate time savings, complication rates, and dosimetry associated with CTF.

Main Methods:

  • Review of initial clinical experience with CTF.
  • Assessment of procedure time, room time, fluoroscopy time, complication rates, and physician dosimetry.
  • Comparison with conventional CT (C-CT) guidance.

Main Results:

  • CTF is effective for guiding interventions in deep organ lesions (pulmonary, pelvic, retroperitoneal).

  • Procedure time is reduced by at least 50% compared to C-CT.
  • Accurate targeting of small, previously inaccessible lesions is achievable.
  • Physician hand exposure is reduced to acceptable levels.

    • Conclusions:

    • CTF enhances efficiency and throughput in interventional radiology departments.
    • CTF provides a valuable tool for accurate guidance in challenging non-vascular interventions.
    • The technology demonstrates potential for improved safety and efficacy.
