Multi-country joint development of new needle biopsy guidance system

Release date: 2009-07-16



A groundbreaking study has shown that a new breast biopsy guidance system can significantly improve the efficiency and comfort of the procedure. This innovative system, developed by researchers from the Robarts Institute in Canada, the University of Western Ontario, and the London Health Science Center, aims to enhance the accuracy and ease of ultrasound-guided breast biopsies.

The system features an electronic tracking robotic arm combined with a braking mechanism, which is connected to an ultrasound transducer. The biopsy needle is guided through this arm, allowing for more precise placement. In the study, both experienced and inexperienced radiologists performed biopsies on breast lesions, comparing the outcomes when using the guidance system versus traditional methods. The results were measured based on factors such as procedure time and accuracy.

The findings revealed that the success rate was 95.9% when using the guided system, compared to 91.3% without it. Additionally, experienced radiologists completed the procedure in approximately 31 seconds, but with the guidance system, the time was reduced by about 10 seconds. These improvements suggest that the system not only enhances accuracy but also reduces patient discomfort and overall procedure time.

The research, which details the technology and its outcomes, was published in the June 2009 issue of *Radiology*, a leading U.S. medical journal. This advancement marks a significant step forward in improving diagnostic procedures and patient care in the field of breast imaging. Shanghai Medical Device Industry Association.
