title: Normal structures on endoscopic ultrasonography: visualization measurement data and interobserver variation.
abstract: Endoscopic ultrasonography is a highly technical procedure requiring considerable experience and knowledge of human anatomy and its variations. Its use in the assessment of a variety of upper and lower gastrointestinal diseases has been valuable. Measurement of structures by endosonography is routinely accomplished although with uncertain accuracy, reproducibility, and interobserver variation.
