Disclosed are a viscosity-standardized combination of solutions and a method of using the solutions for the diagnosis of dysphagia and for radiographic imaging of the oropharynx. This invention is directed to a standardized combination of edible solutions for evaluating human subjects for the presence of dyshagia. Because the solutions have a standard and known viscosity, they promote the systematic study and treatment of swallowing disorders. The combination comprises three solutions: the first a "thin" composition, the second a "nectar thick" composition and the third a "honey thick" composition. The utilities of the subject compositions and methods are several-fold. A primary utility is that by using standardized compositions, consistency in treating dysphagia is promoted. Rather than supplying patients an arbitrarily thickened food or X-ray imaging product, the patient is supplied a composition of known viscosity. The patient's ability to swallow the composition properly i studies (one using the nectar-thick composition, the other using the honey-thick composition) to be compared and contrasted. Moreover, it allows the results from different patients to be compared directly, without variations in viscosity of the imaging agent introducing uncontrolled variables into the comparison.
