光学导航介入性MR的临床应用

目的介绍在光学导航介入性MR引导下经皮穿刺活检及治疗的技术方法，并评价其临床应用价值。方法54例患者，均在光学导航介入性MR引导下进行经皮穿刺活检或治疗。所用设备为Philips公司生产的开放式0．23T常导型MR型检查仪，并配有iPath200光学导航系统。穿刺针采用德国Daum公司的MR兼容性穿刺针。结果本组54例介人性操作均1次穿刺成功，未发现病人出现严重出血、脏器损伤和神经损伤等明显并发症。结论光学导航介入性MR引导下的介人性操作是1种安全、准确的新技术。

Clinical application of interventional MR with optical navigating

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.
