Cone Beam CT Guided Electromagnetic Navigational Bronchoscopy

Electromagnetic navigation bronchoscopy (ENB) is used to access peripheral and central parenchymal lung lesions via endobronchial and transbronchial approach. Traditionally ENB is done under fluoroscopic guidance using C-arm but with development of Cone Beam CT and 3D reconstruction technology, fluoroscopy can be enhanced to much higher resolution and can also provide real time 3D augmentation of the lesion. It also enables the user to obtain a CT of the Chest to confirm the real time location of the lesion and the bronchoscopic biopsy catheter and instruments. This is thought to improve the yield and sensitivity of ENB guided Biopsy of the lung nodules and masses but has not been proven in a prospective trial. With my study, I want to examine the effect of Cone Beam CT with 3D reconstruction on the diagnostic yield and sensitivity of Electromagnetic Navigational Bronchoscopic biopsy of the lung lesions.
