Abstract:
Objective To evaluate the clinical value of virtual US-CT or MRI navigation system for guidance of interventional procedures. Methods Virtual US-CT or MRI fusion navigation system was applied on 47 cases for guiding various interventional procedures. The operating method, success rate, clinical outcome,and complication of the navigating interventional technique were retrospectively analyzed. Thirty-eight cases of hepatic tumors underwent percutaneous needle biopsy and/or radiofrequency ablation (RFA); 4 cases of hepatic abscess underwent percutaneous abscess drainage, 5 cases of musculoskeletal diseases underwent biopsy, RFA or RFA with cementoplasty. Results For 38 cases of hepatic tumors who underwent RFA, 27 acquired complete ablation in one session, no recurrence after 3.0-6. 0 months (median time4. 8 months) follow-up; while the other 11 cases present with no significant change. Five cases of musculoskeletal diseases improved significantly after interventional therapy and pathological diagnoses were also acquired. Four cases of hepatic abscesses were cured after drainage. All cases were free of significant complication, except one local skin thermal damage. Conclusion Virtual US-CT or MRI navigation guiding technique provides mutual aid to different imaging modalities for guiding interventional procedure. After application of navigation system, those interventional procedures may become more convenient, more effective and safer.
