Answer

This uses technology that allows the operator to approach a peripheral lung mass using electromagnetic navigation (EMN) based on virtual bronchoscopy and real-time 3D CT images. The technology has been shown to be capable of reaching peripheral lung masses beyond the reach of the standard bronchoscope in an animal model. [24]

However, a multicenter study by Ost et al, using data from the AQuIRE (ACCP [American College of Chest Physicians] Quality Improvement Registry, Evaluation, and Education) registry to measure and identify the determinants of diagnostic yield for bronchoscopy in patients with peripheral lung lesions, found that EMN had a lower-than-expected yield.
