Endoscopic ultrasound (EUS) is a minimally invasive procedure to assess the gastrointestinal tract for diseases. A special endoscope uses high-frequency sound waves to produce detailed images of the lining and walls of your digestive tract and nearby organs such as the pancreas, liver and the lymph nodes as well. When combined with fine-needle aspiration, biopsies can also be performed for further analysis.
