Abstract:
Scintigraphy is one of several diagnostic procedures used to investigate dysphagia. Several different methods to present the bolus transport have been presented. The normalized condensed image enables quantitative assessments of patterns of bolus transport and a descriptive nomenclature of these patterns: the "L-h-S-E-m-system", based on results of 25 subjects without dysphagia, is suggested. Aberrant patterns were found in 40% of the swallows.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...
