[Positive electroroentgenography for examining the esophagus and stomach].

Results of the clinical use of positive electroroentgenography for examination of the esophagus and stomach in 437 patients are analysed. Different pathology of the esophagus and stomach was detected in 313 patients including esophageal and stomach cancer in 144 patients. Some problems related to the quality of positive electroroentgenograms, parameters and conditions, and some features of positive electroroentgenographic visualization of the esophagus and stomach are discussed. Positive electroroentgenography has been found superior during examination with a double contrast method and in the detection of tumor pathology. Dosimetry of radiation exposure of patients during positive electroroentgenography of the stomach and esophagus was done. Input exposure and integral absorbed doses in electroroentgenography turned out to be lower than those in film roentgenography.
