Abstract
Electromagnetic navigation (EMN) bronchoscopy has revolutionized the tissue acquisition for diagnosis of lung nodules. EMN-guided biopsy has increased the diagnostic yield of flexible bronchoscopy for the peripheral lung lesions. This system provides simultaneous guidance with steerable biopsy instruments to the pre-selected parenchymal lesion. To date, there are more than 60 clinical studies on EMN-guided biopsy. This clinical evidence supports the safety and effectiveness of this procedure. In addition to conventional fluoroscopy, there are several adjunct imaging techniques which can be used to augment the diagnostic yield of EMN-guided biopsy. These imaging techniques include radial probe ultrasound, augmented fluoroscopy, Tomosynthesis-based fluoroscopic navigation, and cone–beam computed tomography. Although the upfront cost of the EMN technology and instrumentation are relatively high, it significantly increases the overall diagnostic yield of the flexible bronchoscopy for diagnosis of pulmonary nodules. This innovation has also demonstrated its utility for certain therapeutic applications for lung cancer. In this chapter, we describe the brief history, prerequisite knowledge, procedural maneuvers, and limitations of EMN bronchoscopy.
