["Cost-benefit" evaluation in the radiological examination of the colon (author's transl)].
The role of radiological examination in detecting the early colonic cancer is considered. A cost-benefit evaluation between conventional barium enema and double contrast enema justifies the use of D.C.E. for the early detection of colonic cancer.
