Roentgenography is an X-ray examination to examine the stomach, from the esophageal entrance to the duodenum, for the presence or absence of lesions. Currently, the main methods used are the filling method, mucosal method, double contrast method, and compression method. By utilizing the advantages of these imaging methods and compensating for their disadvantages, the examination can clarify the presence or absence of lesions in the stomach as a whole, and if a lesion is present, the morphology of the lesion can be depicted in detail. [Refilling method] The stomach must be adequately distended, and 200 to 300 mL of barium sulfate (80 to 100%) is typically used as the contrast agent.
