Summary
A novel robotic device aids prostate biopsies guided by real-time MRI. This system successfully targeted most cancer-suspicious regions, demonstrating feasibility for improved prostate cancer diagnosis.
Area of Science:
- Medical Robotics
- Diagnostic Imaging
- Urological Oncology
Background:
- Prostate cancer diagnosis often relies on transrectal biopsy.
- Previous biopsies may yield inconclusive results, necessitating further investigation.
- Magnetic resonance (MR) imaging offers detailed visualization of the prostate.
Purpose of the Study:
- To evaluate the feasibility of a robotic device for MR-guided prostate biopsy.
- To assess the utility of a remote-controlled, pneumatically actuated robotic system.
- To determine the effectiveness of real-time 3-T MR imaging guidance in robotic prostate biopsy.
Main Methods:
- Prospective study involving 12 men with suspected prostate cancer.
- Multiparametric MR imaging used to identify cancer-suspicious regions (CSRs).
- A remote-controlled, MR-compatible robotic device targeted CSRs for biopsy under real-time MR guidance.
Main Results:
- 17 CSRs were identified in 10 patients.
- The robotic device successfully reached 13 (76%) of the 17 targeted CSRs.
- Biopsies of the remaining CSRs were completed manually.
Conclusions:
- The use of a remote-controlled, MR-compatible robotic device is feasible for transrectal prostate biopsy.
- Real-time 3-T MR imaging guidance enhances robotic-assisted prostate biopsy.
- This technology shows promise for improving the accuracy of prostate cancer diagnosis.
