Ultrasonic real-time guidance for percutaneous puncture

Area of Science:

• Medical Imaging
• Interventional Radiology
• Ultrasound Technology

Background:

• Traditional puncture techniques can lack precise needle guidance.
• Real-time visualization is crucial for accurate and safe interventional procedures.

Purpose of the Study:

• To develop and evaluate a novel sonically guided puncture technique using real-time ultrasound scanning.
• To enhance the safety and ease of percutaneous interventions.

Main Methods:

• A specialized puncture attachment was designed and connected to an ultrasound sector scanner.
• The attachment allows needle introduction within the scanning plane for real-time visualization.
• The technique was applied to various procedures including renal cyst puncture and biopsies.

Main Results:

• Real-time ultrasound provided clear visualization of the needle and target lesion during procedures.
• The technique facilitated easy and safe punctures of both cystic and solid masses.
• Successful applications were demonstrated in renal cyst puncture, pyelography, nephrostomy, renal biopsy, and prostatic biopsy.

Conclusions:

• The developed real-time ultrasound-guided puncture technique improves procedural accuracy and safety.
• This method is versatile and applicable to a range of interventional radiology procedures.
• The technique offers a significant advancement in minimally invasive interventions.
