Electromagnetic Navigational Bronchoscopy-guided Fiducial Markers for Lung Stereotactic Body Radiation Therapy

Abstract

ENB placement of embolization coils as fiducials for lung SBRT image guidance is associated with a low rate of iatrogenic pneumothoraces, and resulted in reliable placement of the fiducials in close proximity to the lung nodule. Embolization coils retained their relative position to the nodule throughout the course of SBRT, and provide an excellent alternative to linear gold seeds.
