Esophageal radionuclide transit tests. Potential false-positive results. 1984

J M Blackwell, and J E Richter, and W C Wu, and R J Cowan, and D O Castell

Esophageal radionuclide transit testing is a sensitive technique for assessing esophageal clearance. Experience with the technique in 150 patients has led to an awareness of several pitfalls which might lead to false-positive results. Potential problems may be grouped into technical factors, clinical aspects, and misinterpretations. Examples of these are presented and techniques to minimize such problems are discussed.

UI	MeSH Term	Description	Entries
D008365	Manometry	Measurement of the pressure or tension of liquids or gases with a manometer.	Tonometry,Manometries
D010528	Peristalsis	A movement, caused by sequential muscle contraction, that pushes the contents of the intestines or other tubular organs in one direction.	Peristalses
D011877	Radionuclide Imaging	The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.	Gamma Camera Imaging,Radioisotope Scanning,Scanning, Radioisotope,Scintigraphy,Scintiphotography,Imaging, Gamma Camera,Imaging, Radionuclide
D003680	Deglutition Disorders	Difficulty in SWALLOWING which may result from neuromuscular disorder or mechanical obstruction. Dysphagia is classified into two distinct types: oropharyngeal dysphagia due to malfunction of the PHARYNX and UPPER ESOPHAGEAL SPHINCTER; and esophageal dysphagia due to malfunction of the ESOPHAGUS.

D004935	Esophageal Diseases	Pathological processes in the ESOPHAGUS.	Disease, Esophageal,Diseases, Esophageal,Esophageal Disease
D004940	Esophageal Stenosis	A stricture of the ESOPHAGUS. Most are acquired but can be congenital.	Esophageal Stricture,Stenosis, Esophageal,Esophageal Stenoses,Stricture, Esophageal
D004947	Esophagus	The muscular membranous segment between the PHARYNX and the STOMACH in the UPPER GASTROINTESTINAL TRACT.
D005189	False Positive Reactions	Positive test results in subjects who do not possess the attribute for which the test is conducted. The labeling of healthy persons as diseased when screening in the detection of disease. (Last, A Dictionary of Epidemiology, 2d ed)	False Positive Reaction,Positive Reaction, False,Positive Reactions, False,Reaction, False Positive,Reactions, False Positive
D005764	Gastroesophageal Reflux	Retrograde flow of gastric juice (GASTRIC ACID) and/or duodenal contents (BILE ACIDS; PANCREATIC JUICE) into the distal ESOPHAGUS, commonly due to incompetence of the LOWER ESOPHAGEAL SPHINCTER.
