试行用于支气管镜肺结节取样的虚拟导航 (VN) 系统
总体目标是评估虚拟导航 (VN) 系统(虚拟导航器)在宾夕法尼亚州好时医疗中心 (HMC) 的肺癌和其他胸部病变的支气管镜评估和组织取样中的作用。 Virtual Navigator 是一个在基于 Windows 的移动计算机上运行的软件包。 计算机最多可接收四个临床图像/视频源,由临床医生为临床目的订购:1) 3D CT(计算机断层扫描)成像扫描; 2)3D PET(正电子发射断层扫描)成像扫描(可选); 3) 气道树内部的支气管镜视频; 4) 气道外扫描解剖结构的超声视频,由支气管内超声 (EBUS) 探头(可选)提供。 在实时引导程序中,虚拟导航器会显示图像,帮助将支气管镜导航至预先指定的胸部病变。
在胸部 CT 扫描中显示可疑外周肿瘤的肺癌患者通常需要接受诊断和分期支气管镜检查,支气管镜检查员会检查可疑肿瘤和任何已识别的胸部中央淋巴结。 对于临床研究,我们考虑两个队列的支气管镜检查性能:1) 一组同意的患者,他们通过 Virtual Navigator 接受图像引导的支气管镜检查; 2) 一个历史对照队列,由最近在我们的医疗中心接受支气管镜检查的患者组成(最先进的支气管镜检查实践)。 该研究的一般假设是,与当前最先进的临床技术相比,集成了 3D 成像、支气管镜检查和 EBUS 图像的图像引导支气管镜检查系统(Virtual Navigator)能够对胸部病变进行更完整的评估和取样。 更具体地说,对于外周肿瘤诊断,子假设是与最先进的支气管镜检查实践相比,VN 系统提高了诊断活检率;对于中央胸部淋巴结分期,子假设是 VN 系统能够比最先进的支气管镜检查实践更多的淋巴结取样。

队列和干预
团体/队列 |
干预/治疗 |
|---|---|
|
历史对照队列
以前接受过临床支气管镜检查的肺癌患者。
该组代表了当前最先进的支气管镜检查实践。
|
|
|
同意的临床支气管镜队列
肺癌患者,计划进行支气管镜检查,同意在 Virtual Navigator 的协助下进行支气管镜检查。
|
Virtual Navigator 引导计算机连接到支气管镜检查硬件,以获取实时支气管镜检查和 EBUS 视频馈送。
标准的 OR 医疗团队(技术人员、临床研究员等)随时待命,并提供标准的临床设施(例如荧光透视、CT/PET 图像查看器)。
我们的技术团队也会在场记录所有程序视频和计算机显示信息。
它还在引导过程中操作引导计算机,并在出现意外问题时提供任何帮助。
参与者的临床支气管镜检查将由放射成像管理系统记录。
