Endoscopy, 1999
Areas of application for endosonography can be roughly divided into three categories: standard diagnostic examination; operative diagnostic examination (fine-needle aspiration); and operative therapeutic procedures. Nevertheless, endoscopic ultrasonography remains a single technique, in which the physician can not only raise a suspicion of a particular

Diagnostic sonography is experiencing a breath-taking period of technological advancement. Ultrasound contrast agents, new imaging techniques, and handheld instruments will play a role in facilitating more diagnostic power in high-end imaging and insuring more widespread use of diagnostic sonography in medicine in general.

Veterinary Clinics of North America: Small Animal Practice, 1993
The basic principles of diagnostic ultrasonography are discussed. Normal and abnormal ultrasonographic appearances of the major organs are presented in tables and with illustrations. A description of the current status of neurosonology with illustrations of hydrocephalus is also presented.

Endoscopy, 1998
Endoscopic ultrasonography (EUS) is nowadays a clinically relevant technology and its findings can have a major impact on patient management. This technique is currently indicated for staging digestive cancers, assessment of submucosal tumors, diagnosis of intestinal wall infiltrative diseases, common bile-duct stones and gut neuroendocrine tumors.

Sound is a mechanical vibration of particles in a medium around an equilibrium position. Sonic waves require a medium of a molecular nature in order to propagate. The highest frequency sound audible to the human ear is 20,000 cycles per second or 20 kiloHertz (kHz). Sound waves above this frequency are described as ultrasound.

Gastroenterology Nursing, 1990
Endoscopic ultrasonography is a new and interesting technique. It is the only imaging technique that provides images of the gastrointestinal wall. Because of the high frequency used in EUS, it may provide high resolution images of gastrointestinal organs such as the pancreas. Although the equipment used for EUS is similar to that used for more familiar

Ultrasonography of the Pancreas
Radiologic Clinics of North America, 2012Although the pancreas is often thought of as an organ that is difficult to explore using ultrasound (US), because of its deep retroperitoneal location, with the appropriate technique it can be studied successfully in most patients. In this article, the authors discuss the use of available US techniques in the diagnosis of the most common pancreatic ...
