Summary
A new modified coaxial technique enables safe and efficient biopsies of small or deep lesions using computed tomographic (CT) guidance. This method allows for multiple tissue samples to be obtained quickly and repeatedly.
Area of Science:
- Medical imaging
- Interventional radiology
- Oncology
Background:
- Biopsy of small or deep lesions presents technical challenges.
- Accurate tissue sampling is crucial for diagnosis and treatment planning.
Purpose of the Study:
- To describe a modified coaxial technique for CT-guided biopsy.
- To evaluate the safety, efficiency, and repeatability of this technique.
Main Methods:
- A 22-gauge needle was used coaxially through an 18-gauge introducing needle.
- Computed tomographic (CT) guidance was employed for precise needle placement.
- Aspiration biopsy was performed using the coaxial system.
Main Results:
- The modified coaxial technique facilitates biopsies of small or deeply situated lesions.
- The procedure allows for safe, expeditious, and repeated tissue sampling.
- CT guidance ensures accurate targeting and minimizes complications.
Conclusions:
- The described modified coaxial technique is a valuable tool for CT-guided biopsy.
- This method improves the ability to obtain multiple samples from challenging lesions.
- It offers a safe and efficient approach for tissue acquisition in interventional radiology.
