Electromagnetic navigation bronchoscopy versus virtual bronchoscopy navigation for improving the diagnosis of peripheral lung lesions: analysis of the predictors of successful diagnosis

Feasibility study of a novel wireless localization technique using radiofrequency identification markers for small and deeply located lung lesions

“…A recent study revealed that adding electromagnetic navigation (EMN) to CBCT significantly increased bronchoscopic navigation success to 87.5% compared with CBCT or EMN alone (76.3% and 52.2%, respectively). 16 Because EMN can potentially guide the bronchoscope to an ideal site adjacent to targets that appear unreachable by conventional bronchoscopy, 17,18 EMN under CBCT imaging might improve marker placement accuracy in less time and reduce the radiation exposure.…”

Intraoperative margin assessment by wireless signals in thoracoscopic anterior (S3) segmentectomy using a radiofrequency identification marker

“…Although intrapulmonary sites accessible via bronchoscopy depend on an individual’s bronchial anatomy, this critical issue can be overcome using CBCT-guided bronchoscopy. In the current case, the RFID marker was placed under CBCT-guided bronchoscopy in combination with ENB because the tumor had no apparent bronchus sign [ 10 ]. Regarding the capability of bronchoscopy to reach peripheral pulmonary lesions, newer technologies have been introduced to improve the rate of successful bronchoscopic navigation to peripheral pulmonary nodules [ 11 ].…”

Diagnostic Performance of Electromagnetic Navigation versus Virtual Navigation Bronchoscopy-Guided Biopsy for Pulmonary Lesions in a Single Institution: Potential Role of Artificial Intelligence for Navigation Planning

“…Thereafter, a CT scan will be performed on the same day with respiratory sensors in place [ 10 ]. Several studies have reported diagnostic rates higher than conventional bronchoscopy [ 11 , 12 ]. The Archimedes virtual bronchoscopic navigation (VBN) system (Broncus Medical, San Jose, CA, USA) is an image-guided navigation system mainly applied to diagnose lung nodules.…”

“…The system allows for vessel mapping, providing the best path to avoid blood vessels, which allows a combination of bronchoscopic transparenchymal nodule access (BTPNA), thereby reducing bleeding complications [ 13 ]. However, the comparison of the differences in the yield of ENB and VBN for diagnosing lung lesions is limited [ 12 ]. A meta-analysis showed diagnostic yields of 67% for ENB and 72% for VBN, with a substantial variation in the yield affected by the use of a guide sheath, ultrathin bronchoscope, and radial probe endobronchial ultrasound (R-EBUS) [ 14 , 15 ].…”
