Endobronchial Ultrasound Brochoscopy (EBUS)

Performed in a Hospital setting

Purpose of the Procedure

If you have been diagnosed with lung cancer (or initial tests are strongly suggestive of it), endobronchial

ultrasonography may be ordered alongside traditional bronchoscopy.

Unlike bronchoscopy, which directly visualizes airways through a viewing scope, EBUS can help doctors see beyond the airway tissues using refracted sound waves.

Endobronchial ultrasound can be used to determine the extent of tumor invasion in the central airways, such as might occur with squamous cell carcinomas (which typically start in the airways) and metastatic lung adenocarcinomas (which can spread from the outer edges of the lungs and invade the central lung)

What is an EBUS ultrasound?

Endobronchial Ultrasound Bronchoscopy (EBUS) Endobronchial ultrasound (EBUS) is a minimally invasive but highly effective procedure used to diagnose lung cancer, infections, and other diseases causing enlarged lymph nodes in the chest.

It may be performed during a bronchoscopy, to provide further information to diagnose or determine the stage of a lung cancer

Endobronchial ultrasound is considered safe and minimally invasive, neither exposing you to ionizing radiation nor surgery. Typically performed on an outpatient basis, it can also help diagnose certain inflammatory lung diseases that cannot be confirmed with standard imaging tests.
