Double-contrast examination of the stomach: 100mm fluorography vs. full-size radiography

Full-size radiographs and 100mm fluorographic spot views taken with an image intensifier were compared during double-contrast examination of the stomach. Differences in image quality between the two modalities were small; there was also a small decrease in absorbed dose, since fluoroscopy comprised more than half of the total dose. The authors recommend that 100mm spot views be used routinely in double-contrast examination of the stomach.
