Ultrasound fusion tech aims to sharpen needle accuracy in procedures
NCT ID NCT02563444
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a new ultrasound fusion system that combines ultrasound with CT scan data to guide needle placement in tissue lesions. Researchers compared the needle path shown by the system to the actual path on a CT scan in 25 patients. The goal was to see if this technology could improve accuracy, save time, and reduce radiation exposure.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Ultrasound fusion guiding system (TUS A-500, Aplio 500)
- What this could lead to
- If successful, this could improve the accuracy of needle placement during biopsies or treatments, potentially reducing the need for repeat procedures and lowering radiation exposure.
- What could go wrong
- This is a small, early-stage study with only 25 participants, and it only tested accuracy in a controlled setting. The results may not apply to real-world procedures or all types of lesions.
