Endoscopic ultrasound (EUS)

What is an endoscopic ultrasound?

An internal scan that allows a consultant to examine the organs and structures in the chest and abdomen in detail using high-frequency sound waves to produce detailed images of the lining and walls of your digestive system and chest, it can also include neighbouring organs such as the liver and pancreas, and lymph nodes.

During the endoscopic ultrasound, a thin, flexible tube (endoscope) with a small probe (ultrasound transmitter) on the end is passed through the mouth to the area being examined. The ultrasound transmitter emits harmless sound waves which produce the high frequency images.

These images are relayed onto a screen and analysed by a consultant.
