Compensation filtration in paediatric double contrast barium enema examinations.

A prospective study of double contrast barium enema examinations performed on 42 children aged 2.5-19 years (mean age 12.3 years) showed that compensation filtration improved the radiographic quality in 32 (76%) of the examinations; it also reduced radiation dosage in all patients. In no examination was the use of a filter deleterious. Compensation filtration is recommended for all paediatric double contrast barium enema examinations to improve radiographic quality and reduce radiation dosage.
