If your doctor needs more information about the health of your lungs, you may be scheduled for an endobronchial ultrasound (EBUS) evaluation.
EBUS involves the insertion of a long, flexible tube through the mouth or nose, into the lungs. A specialized instrument, called a bronchoscope, allows physicians to closely examine lung tissue. Ultrasound uses high-frequency sound waves to produce images.

In an EBUS procedure, a bronchoscope is fitted with an ultrasound transducer at its tip and passed into the windpipe. This is done with local anesthesia and light sedation.
The ultrasound instrument can be pointed in different directions to look at lymph nodes and other structures in the mediastinum, the area between the lungs.
If suspicious areas such as enlarged lymph nodes are seen, a hollow needle can be passed through the bronchoscope to get samples of them. The samples are then sent to a lab to be looked at under a microscope.
After the Endobronchial Ultrasound Test
When the anesthetic wears off, your throat may be scratchy for several days. Your cough reflex will return in one to two hours after the test. You won't be allowed to eat or drink until your cough reflex returns.
