Transgastroscopic Ultrasonography
Endoscopy, 1976A newly designed ultrasonography probe is presented which can be advanced through the instrumentation channel of an operative endoscope (TGF-Olympus). The A-scan allows the differentiation between solid and cystic masses in the upper abdomen leading to gastric impression.

Surgical Clinics of North America, 2001
Pancreatic abnormalities usually are detected on US when it is used for screening patients with abdominal pain and for assessment of the gallbladder and bile ducts. Pancreatic visualization is limited by bowel gas, but with experienced sonographers and newer techniques, including harmonic imaging and oral contrast US, diagnosis of pancreatic ...

International Ophthalmology Clinics, 1978
Ultrasonography and the more recently developed technique of computerized tomography (see the preceding chapter) should be used concurrently in the evaluation and diagnosis of suspected orbital pathology. Ultrasonography is easily performed and safe; it has no known complications or contraindications.

Fetal growth is a dynamic process determined by a combination of genetic, intrauterine, and environmental influences. However, assessment of fetal growth with a onetime measurement is standard clinical practice, despite recognition that a single measurement can only indicate size, not growth.

Ultrasound Quarterly, 2011
Endoanorectal ultrasonography (EARUS) may be used for diagnosing various anorectal disorders. EARUS is easy to perform, has a short learning curve, and causes less discomfort than routine digital examination. Anal sphincters can be clearly visualized, and one can easily distinguish between the internal (hypoechoic) and external (hyperechoic) anal ...

Journal of Endourology, 2001
The use of laparoscopic ultrasonography (LUS) allows visualization of tissues beyond the two-dimensional laparoscopic picture, enhancing the amount and quality of information available to the surgeon. Linear-array transducers with frequencies of 7.5 to 10 MHz are typically used for LUS, employing B-mode scanning and color Doppler capability on probes ...

Ophthalmic Plastic & Reconstructive Surgery, 1994
Lacrimal ultrasonography (echography) evaluates lesions in that drainage system in a painless, noninvasive way in the office. The technique complements other imaging methods and can be correlated with histological results. The authors survey the principles and technique and describe the normal ultrasound, indications, applications, and limitations ...

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.
