Applying value of interventional MR-guided biopsies in musculoskeletal lesions
Abstract：Objective:To introduce the procedures and evaluate the applying value of the iPath 200 interventional MR-guided biopsies in musculoskeletal lesions. Methods:24 patients with musculoskeletal lesions underwent iPath 200 interventional MR-guided percutaneous biopsies. All patients were performed under 0.23 T open MRI system (Proview, Philips Medical System) with optical tracking system (iPath 200, Philips Medical System). The needle was MR-compatible (Daum, Germany). 6 of 24 patients underwent MR contrast-enhance examination during the biopsy. The contrast agent used was gadopentetate dimeglumine (Gd-DTPA; Magnevist, Schering, Berlin, Germany) 0.4ml/kg body weight. 10 of 24 patients underwent a subsequent open surgical biopsy or surgical operative treatment. Results:The sample of MR-guided biopsy was estimated to be sufficient and histopathological diagnosis was got in all cases (24/24). In 10 patients who underwent subsequent open surgical biopsy or surgical operative treatment, primary diagnosis and final diagnosis was coincidence essentially (10/10). No complications such as severe bleeding or neurological damage took place.Conclusion:iPath 200 interventional MR-guided percutaneous biopsy in musculoskeletal lesions is an accurate and safe technique.
