Situation: A radiograph of an RAO projection taken during an esophagram demonstrates incomplete filling of the esophagus with barium. What can the technologist do to ensure better filling of the esophagus during the repeat exposure?

When using thin barium, have the patient drink continuously during the exposure. With thick barium, have the patient hold 2-3 spoonfuls in the mouth and make the exposure immediately after swallowing

Situation: A series of radiographs taken during an Upper GI reveals that the stomach mucosa is not well visualized.
