Endoscopic ultrasound (EUS) is an imaging technique that uses sound waves to create computer images of the inside of the upper and lower gastrointestinal tract. The addition of ultrasonic imaging also allows examination of organs in close proximity to the upper and lower gastrointestinal tracts.

Ultrasound images are created when a high frequency sound wave emitter projects sound waves at the area to be examined. A computer analyzes the reflected wave patterns and creates images of the observed area. In a sense this allows the physician to see objects through intervening tissue. For instance an organ may be examined even though the probe is hidden inside the intestine.

By combining ultrasound with traditional endoscopy, physicians have more imaging options.

Because the ultrasound emitter is inside the body, images are much more detailed than images from a device outside the body. As in standard endoscopy, this allows the physician to view the inside of this area of the body, as well as insert instruments to remove tissue samples (biopsy).
