The state of radiographic technique in the examination of the colon: a survey
RF Thoeni and AR Margulis
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 barium enema procedures are still the standard methods of
radiographic assessment of the colon; the double- contrast, barium enema
examination is now used more frequently, especially in conjunction with the
single-contrast barium 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. Water-soluble contrast media are administered more frequently.
The use of special radiographic procedures to evaluate the colon has
decreased.
