Abstract
The results of an extensive, multiple choice questionnaire sent to 113 leading medical centers in the world (100 centers responded) were analyzed and compared to those of a similar survey from 1968. Single-contrast and double-contrast Ba enema procedures are still the standard methods of radiographic assessment of the colon: the double-contrast, Ba enema examination is now used more frequently, especially in conjunction with the single-contrast Ba enema; preparation of the colon is now more meticulous; and drugs are added more frequently to the barium enema. Equipment has become more sophisticated through increased use of image intensifiers, television, and remote controls. More use is made of videotapes. H2O-soluble contrast media are administered more frequently. The use of special radiographic procedures to evaluate the colon has decreased.
