A new device improves computed tomography (CT)-guided biopsy accuracy by using external radiopaque landmarks to predict the needle path. This reduces the need for repeat localization scans, enhancing procedural efficiency.

Area of Science:

  • Medical Imaging
  • Surgical Technology
  • Interventional Radiology

Background:

  • Computed tomography (CT)-guided biopsies are crucial for tissue diagnosis but can be limited by needle placement accuracy.
  • Repeated localization scans increase radiation exposure and procedural time.
  • Accurate needle path anticipation is essential for efficient and safe biopsies.

Purpose of the Study:

  • To introduce a novel device designed to enhance needle placement accuracy in CT-guided biopsies.
  • To reduce the number of localization scans required during CT-guided procedures.
  • To improve the overall efficiency and safety of CT-guided biopsy techniques.

Main Methods:

  • Development of a device incorporating external radiopaque landmarks.
  • Utilizing the device to provide an accurate anticipation of the needle path.
