endobronchial ultrasound
Also written as: EBUS — Endobronchial Ultrasound
Minimally invasive procedure using ultrasound guidance through a bronchoscope to visualize and biopsy mediastinal structures.
Full Definition
Endobronchial ultrasound (EBUS) is a bronchoscopic technique that combines real-time ultrasound imaging with bronchoscopy to visualize structures adjacent to the airways, particularly mediastinal and hilar lymph nodes. This procedure allows for precise needle aspiration of suspicious lesions while minimizing patient risk. EBUS has become a standard diagnostic tool in thoracic oncology for staging lung cancer and diagnosing mediastinal masses. The technique provides high diagnostic yield while avoiding more invasive surgical procedures.
Usage
Usage note: Often abbreviated as EBUS; distinguish from EUS (endoscopic ultrasound) used in gastroenterology.
