 Radiological diagnosis of esophageal intramucosal carcinomas was reviewed in accordance with the new subclassification proposed by the Japanese Society of Esophageal Diseases.

 Eighty percent of the superficial elevated type of m2 and m3 cancers were recognized on the initial x-ray examination, while the superficial depressed type of m1 and m2 cancers were hardly pointed out.

 On the detailed examination of the superficial elevated type, there was little relation between x-ray findings and the extension by air. As for the superficial depressed type, lesions less than 1 cm in size showed no marginal irregularity, but barium shadows were visualized by double contrast radiography with an adequate amount of air. Lesions more than 1 cm in size showed interrupted folds and collection of the contrast medium, and marginal irregularity was observed in cases of m3 cancer by double contrast radiography.
