What is endoscopic ultrasound?

Also known as: EUS.

Ultrasound is a medical imaging test that uses sound waves to produce pictures of organs and systems inside the body. When more detailed images of portions of the digestive system are needed, a patient might receive an endoscopic ultrasound. This involves performing an ultrasound using an endoscope, or a long, thin, flexible tube that is passed inside the body.
