摘要：

Study objective: To determine the feasibility of using real-time bronchoscope position technology coupled with previously acquired three-dimensional CT data to enhance transbronchial needle aspiration (TBNA). Design: Eight swine were given percutaneously created target lesions for TBNA. a miniature position sensor was placed at the tip of a bronchoscope, and real-time position information during bronchoscopy was presented on a monitor simultaneously displaying previously acquired three-dimensional CT data. Interventions: TBNA of target lesions and submucosal ink-spot injection of computer-generated targets. Measurements and results: TBNA specimens revealed successful aspiration of target material. Distances between ink marks made at computer-generated tracheal targets varied, on average (+/- SD), 4.2 mm +/- 2.6 mm from predetermined computer-distance coordinates. Conclusion: Real-time bronchoscope position technology coupled with previously acquired CT images may aid with TBNA of nonvisible extrabronchial lesions.
