Adequate large intestine distention and mucosal covering has been obtained when

C) the barium pool is limited to half the intestinal diameter.
D) the barium is pooled in the dependent surface.

Question

Quizplus · Accepted Answer

A thin coating of barium covering the mucosal surface indicates adequate distention and mucosal covering of the large intestine. Choice A is not specific enough in terms of the extent of the folds to determine adequate distention. Choices C and D both suggest suboptimal distention and pooling of barium, which may lead to missed pathology.
