Roentgenography is an X-ray examination used to check for lesions in the small and large intestine. It is broadly divided into small intestine X-ray examinations and large intestine X-ray examinations. [Small intestine X-ray examination] (1) Oral administration method: This is a method in which a contrast agent is taken orally and then observed over time following a stomach X-ray examination (gastroduodenal examination). This method can clarify the state of the margins due to the degree of tension of the small intestine and the poor extension of the complex mucosal folds caused by movement. However, it is difficult to determine minute lesions due to overlapping of the intestinal tract. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
