[Dynamic esophageal scintigraphy by a condensed imaging method]

The paper is concerned with preliminary evaluation of a method of condensed imaging during processing of the results of dynamic esophageal scintigraphy to detect motor evacuatory function of the esophagus. Altogether 34 patients (20 patients with primary esophageal cancer and 14 without G. I. tract pathology) were investigated. Comparison of the results of analysis of dynamic esophageal scintigraphy by a method of condensed imaging and standard methods of diagnostic data processing has shown that a condensed image of the esophagus objectively reflects some passage features of a food lump in the organ. Condensed imaging seems superior for analysis of the results of investigation and diagnostic data storage. However, this method must not be regarded as an alternative one ruling out a necessity of analysis of esophageal histograms and calculation of RP transport in the esophagus.
