[Necessary radiological items for radiation therapy of esophageal cancer].
Necessary items for radiation therapy of an esophageal cancer are discussed in detail. These radiological items can be dissolved through the radiological findings by use of the fine double contrast method of treating the esophagus. One method is to dissolve the infiltrative depth of the esophageal cancer; the other is the radiological diagnostic method to dissolve the effect of the radiation therapy on the esophageal cancer. In fact, regarding the former, the classification of the X-ray type is essential and depends upon the infiltrative depth of the cancer and, for the latter, the radiological findings before and after irradiation must be compared.
