Endobronchial Ultrasound (EBUS) : EBUS is usually performed under general anesthesia using a laryngeal masque. It has a linear ultrasonography with a 7.5 MHz frequency. The distal part of the endoscope contains a water filled balloon used as a liquid interface, camera, light source and a working channel. The needle is protected by a sheath to prevent working channel damage. The endoscope is connected to a processor that reflects both endobronchial and ultrasound images on a screen. EBUS - TBNA : EBUS - Transbronchial needle aspiration EBUS - TBCB: EBUS - Transbronchial Cryo Biopsy
