A radiological contrast product comprising a non-toxic radiopaque salt selected from the group consisting of barium titanate and barium zirconate and a method for conducting radiological examinations of the gastro-intestinal tract of a mammal with said product is disclosed herein.
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.
A method of manufacturing barium titanate (BaTiO.sub.3) (BaTiO(C.sub.2 O.sub.4).sub.2. 4H.sub.2 O), is by pyrolysis of barium titanyl oxalate, an provided in which aqueous solution of barium chloride (BaCl.sub.2) is added dropwise while stirring vigorously to an aqueous solution comprising a mixture of oxalic acid (H.sub.2 C.sub.2 O.sub.4) and titanium oxychloride (TiOCl.sub.2) having a temperature in the range from 20.degree. to 60.degree. C. to form barium titanyl oxalate, the resultant precipitate being calcined at a temperature in the range from 960.degree. to 1200.degree. C.
A detectable device for collecting samples consists of a collecting scoop and a handle extending outwardly therefrom. The detection of the device is improved by uniformly dispersing at least one radio-opaque substance within a dispersing medium of its material.
