[Water-soluble contrast media with increased viscosity for the diagnosis of diseases of the paranasal sinuses, bronchi and esophagus].
Water-soluble contrast agents with one of the polymers, cellulose derivatives or polyvinyl alcohol, were used in contrast examinations of paranasal sinuses, bronchi, and esophagus. Experiments have demonstrated the advantages of contrast agents basing on polymers as against the traditional oil-containing agents. Method for double-contrast examination of maxillary and frontal sinuses has been developed. Lowered concentrations of water-soluble contrast agents (i. e. diluted with distilled water) are recommended to be used, this permitting to save the reagents. A table of recommended dilutions of contrast media is presented. A total of 245 patients were examined, making use of contrast media of high viscosity.
