title: Compensation filtration for decubitus radiography during double-contrast barium enema examinations.
abstract: Lateral decubitus images obtained during double-contrast barium enema examinations may be difficult to interpret because of the large difference in density between the various parts of the radiographs. Several types of filters are described which can be used to rectify this problem, thus improving the quality of the decubitus radiographs and achieving a slight reduction in radiation exposure.
