| 摘 要： | 目的:验证应用计算机辅助导航系统标记肺部小结节这项新的定位技术的可行性。方法:四只试验猪在经皮建立肺部小结节模型后进行多层螺旋CT扫描,然后将CT扫描数据传输到计算机辅助导航系统,利用体表标记物进行注册,固定有万能适配器的穿刺针在导航仪的指引下穿刺到小结节模型注入亚甲蓝进行定位,并用胸腔镜切除肺部小结节。结果:共建立肺部小结节模型20个,在CT上20个小结节模型直径为(15.2±0.3)mm。组织病理检查显示所有小结节模型均被成功定位和切除。结论:计算机辅助导航系统可在术前对肺部小结节进行准确定位。

| Abstract: | Objective Thoracoscopy has limits in the detection of small pulmonary nodules,which are invisible and/or impalpable during surgery.Methods to localize such lesions,including the methylene blue injection or the introduction of a hooked-wire under the guidance of CT,have some limitations.We are developing a new technique using image-guided navigation system for localization of small pulmonary nodules before thoracoscopic surgery.Four pigs were spiral-computed tomography(MSCT)scanned after given percutaneously... |
