Abstract:
Objective To introduce the procedures and to evaluate the application value of the optical navigating interventional MR-guided percutaneous biopsies and therapies. Methods Thirty-five of 54 patients (33 males, 21 females) underwent percutaneous biopsies and 19 of 54 patients underwent percutaneous therapies under optical navigating interventional MR-guidance. The age ranged from 9 months to 78 years (mean 38.8 years). All patients were performed under a 0.23 T open MRI system (Proview, Philips Medical System) with optical navigating system (iPath 200, Philips Medical System). The needle and bone biopsy drill were MR-compatible (Daum, Germany). Results Punctures were accurate in all patients (54/54). 33 of 35 biopsies got the pathological diagnosis. All therapies (19/19) got the definitive curative effect. All patients had no obvious complications, such as severe hemorrhage, viscera or nerve injury.Conclusion iPath 200 interventional MR-guided percutaneous biopsies and therapies are accurate and safe techniques.
