Endosonography-guided cholangiopancreatography [PDF]

open access: possibleGastrointestinal Endoscopy, 1996
Detailed imaging of the common bile duct and main pancreatic duct is possible with endosonography. Utilizing a custom manufactured flexible needle, we have developed a technique of performing endosonography-guided cholangiopancreatography (EGCP).Of 205 patients undergoing ERCP, complete ductography was not possible in 11 patients.

Fundamentals of Endosonography

Gastrointestinal Endoscopy Clinics of North America, 1992
In this article the fundamentals of endosonography are discussed. Because ultrasonography consists of acoustic waves, some basic principles of these mechanical waves and how transducers convert electrical energy to acoustic waves are first considered. The concepts of resolution, penetration, and attenuation are explored. The origin of ultrasound echoes

Principles of endosonography and imaging

Gastrointestinal Endoscopy Clinics of North America, 2005
Accurate interpretation of ultrasound images requires knowledge of the principles of ultrasound and how it interacts with tissue. This article outlines the important principles that every endosonographer should know and provides clinical implications to make the material relevant to endosonographers.

Exploring the Role of Endosonography

Scandinavian Journal of Gastroenterology, 1996
Endosonography (ES) or endoscopic ultrasonography has undergone very rapid development and has now become an important imaging technique for gastroenterologists all over the world. Endosonography is currently used in a wide field of gastrointestinal diseases, most of which are in the upper gastrointestinal tract.
