In recent years, there have been notable advancements in the guidance technologies for peripheral bronchoscopy, including newer electromagnetic navigation platforms, cone beam CT, augmented fluoroscopy, digital tomosynthesis, and robot-assisted bronchoscopy.1-7 As a result, multiple recent trials evaluating the performance of these technologies have been reported. The most frequently employed assessment metric is diagnostic accuracy, frequently termed diagnostic yield (DY) in the bronchoscopy literature, yet there remains no standardized approach to measurement of this outcome in studies of bronchoscopy.
