Initial Results

Most of the existing MRI guided robotic needle guide systems have been limited to research purposes and have not progressed towards clinical applications due to complex and bulky structures. The ‘device-to-image’ registration step further complicates the operation and significantly increases the overall procedure time. To address limitations, we developed an MRI guided transperineal prostate biopsy guide system that uses the concept of a ‘fixed coordinate device’ to simplify the overall biopsy procedure and eliminate the registration step, making the procedure more clinically friendly. We performed proof-of-concept targeting experiments using an agar phantom under 3T MRI. The targeting results were analyzed, and initial results prove that the simplified intervention concept would well be feasible. We plan to extend the study further to identify error components.

Abstract In clinical routine, the prostate biopsy procedure is performed with the guidance of transrectal ultrasound (TRUS) imaging to diagnose prostate cancer. However, the TRUS-guided prostate biopsy brings reliability concerns due to the lack of contrast difference between prostate tissue and lesions. In this study, a novel hydraulic needle delivery system that is designed for performing MRI-guided prostate biopsy procedure with transperineal approach is introduced. The feasibility of the overall system was evaluated through in-vitro phantom experiments under an MRI guidance. The in vitro experiments performed using a certified prostate phantom (incorporating MRI visible lesions). MRI experiments showed that overall hydraulic biopsy needle delivery system has excellent MRI compatibility (SNR Loss < 3%), provides acceptable targeting accuracy (average 2.05±0.46 mm) and procedure time (average 40 minutes).
