A new puncture guide simplifies computed tomography (CT)-guided procedures, enhancing accuracy and safety. This device improved first-attempt success rates for CT-guided punctures, making them more reliable.

Area of Science:

  • Medical Imaging
  • Interventional Radiology
  • Surgical Technology

Background:

  • Computed tomography (CT)-guided punctures are crucial for tissue sampling and treatment.
  • Accuracy and safety are paramount in CT-guided procedures.
  • Existing methods may present challenges in needle guidance.

Purpose of the Study:

  • To assess a novel puncture guide designed for CT-guided procedures.
  • To determine if the device simplifies, improves accuracy, and enhances safety.
  • To evaluate the efficacy of this adjunctive guidance tool.

Main Methods:

  • Seventeen patients underwent CT-guided punctures (10 thoracic, 7 abdominal/pelvic lesions).
  • A laser guide was used in conjunction with the new puncture guide device.

  • The device generated a streak artifact to visualize the needle path.

    • Main Results:

    • Successful puncture on the first attempt was achieved in 15 out of 17 patients.
    • The streak artifact was consistently visible, clearly indicating the needle's trajectory.
    • The mean deviation between the artifact angle and needle angle was minimal (1.1 degrees).

    Conclusions:

    • The puncture guide offers significant benefits for CT-guided procedures.
    • Key advantages include a visible artifact for target localization and needle support.
    • The device demonstrably enhances accuracy and safety in CT-guided punctures.
