Diagnosing lung cancer using a flexible bronchoscope is a safe procedure with a very low risk of complications. Bronchoscopy has high diagnostic accuracy for endobronchial lesions, but it falls short when sampling peripheral lesions. Therefore, several modalities have been invented to guide the bronchoscope to the lesion and confirm the location of the tumor before tissue sampling. Fluoroscopy is used during bronchoscopy to provide a 2D X-ray image of the thorax during the procedure. The bronchoscope and tools will be visible, as well as lesions if larger than 2.0-2.5 cm. Radial endobronchial ultrasound (rEBUS) consists of an ultrasound probe, small enough to be inserted into the working channel of the bronchoscope. The ultrasound probe is used to differentiate between consolidated tissue, such as tumor tissue, and normal air-filled lung parenchyma. Electromagnetic navigation bronchoscopy (ENB) creates a 3D model of the bronchial tree from computed tomography (CT) scans of the patient. Prior to the bronchoscopy, a route from the trachea to the lesion is planned, to create real-time guidance of the bronchoscope to the lesion during the procedure, similar to the Global Positioning System. The aim of this article is to describe a stepwise approach to performing bronchoscopy with rEBUS and fluoroscopy, bronchoscopy with ENB, rEBUS, and fluoroscopy. In the discussion section, the pros and cons of each modality will be discussed.
