Endoscopic Ultrasound

Endoscopic Ultrasound (EUS) is a medical procedure in which endoscopy is combined with ultrasound to obtain imaging of internal organs such as the esophagus, stomach, pancreas and rectum. An endoscope with a small ultrasound device at the tip uses high-frequency sound waves to create detailed images of these organs.

EUS is also used to evaluate known abnormalities including lesions detected on a prior endoscopy, CT scan, or MRI. It can also help determine the extent (stage) or spread of certain cancers of the digestive system. EUS allows your physician to assess the depth of a cancer and whether it has spread to adjacent lymph nodes. A Fine Needle Aspiration (FNA) may be used to biopsy fluid or tissue during an EUS to establish a tissue diagnosis and to help determine proper treatment.
