In the mid-1950s, a commercialized ability to capture the moving pictures of television onto magnetic tape (with a video tape recorder) was developed. This soon led to the addition of the "video-" prefix to the words fluorography and fluoroscopy, with the words videofluorography and videofluoroscopy attested since 1960. [53]
The problem can occur when the movements involved in swallowing are restricted due to a tumor, any type of blockage, or paralysis after a stroke. Besides the motor problems, swallowing can be impaired due to sensory dysfunction, meaning when sensation (the ability to feel) is lost or reduced anywhere in the throat area.
An upper gastrointestinal series, also called a barium swallow, barium study, or barium meal, is a series of radiographs used to examine the gastrointestinal tract for abnormalities. A contrast medium , usually a radiocontrast agent such as barium sulfate mixed with water, is ingested or instilled into the gastrointestinal tract, and X-rays are ...
Photofluorography (sometimes called just fluorography) is photography of X-ray images from a fluorescent screen. [1] It is commonly used in some countries for chest X-ray screening, e.g. to diagnose tuberculosis (see Abreugraphy for more information on such usage of this technique).
Swallowing, also called deglutition or inglutition [1] in scientific contexts, is the process in the body of a human that allows for a substance to pass from the mouth, to the pharynx, and into the esophagus, while shutting the epiglottis. Swallowing is an important part of eating and drinking.
Abreugraphy receives its name from its inventor, Dr. Manuel Dias de Abreu, a Brazilian physician and pulmonologist.It has received several different names, according to the country where it was adopted: mass radiography, miniature chest radiograph (United Kingdom and United States), roentgenfluorography (Germany), radiophotography (France), schermografia (Italy), radioscopy (Spain) and ...
Fluorescent dyes, with no maturation time, offer higher photo stability and brightness in comparison to fluorescent proteins. In terms of brightness, luminosity is dependent on the fluorophores’ extinction coefficient or ability to absorb light, and its quantum efficiency or effectiveness at transforming absorbed light into fluorescently emitting luminescence.
As globus sensation is a symptom, a diagnosis of globus pharyngis is typically a diagnosis of exclusion.If globus sensation is presenting with other symptoms such as pain, swallowing disorders such as aspiration or regurgitation (dysphagia), weight loss, or voice change, [10] an organic cause needs to be investigated, typically with endoscopy.
