Endobronchial ultrasound: a minimally invasive technology to assist diagnosis of thoracic diseases

Abstract

The endobronchial ultrasound is a minimally invasive technique that simultaneously associates ultrasound and bronchoscopy, to visualize lung nodule or masses, airway wall, and structures adjacent to the tracheobronchial tree. Endobronchial ultrasound has been incorporated into clinical practice all over the world because of its low risk and high diagnostic yield in neoplastic and non-neoplastic disease.
