Abstract

Endoscopic ultrasonography (EUS) was developed to use radial and linear array to evaluate the luminal wall and adjacent tissues in the gastrointestinal (GI) tract. One of the most important roles of EUS has been in the evaluation and local staging of GI malignancies. The higher resolution of the high-frequency ultrasound (HFUS) probe provides a better definition of the GI wall layers, and therefore yields a better accuracy in the study of small or superficial lesions of the GI tract. HFUS probes can be used in tumor staging in nonbulky lesions and depth evaluation of superficial early cancer prior to endoscopic therapy. The development of intraductal ultrasonography (IDUS) based on special miniprobes has advanced the study of the pancreatico-biliary tree and the duodenal ampulla. IDUS has also been used in the assessment of response to radiation therapy, by measuring the bile duct thickness before and after treatment.
