Abstract
The volume of gas in the intestinal tract of nine normal subjects was determined using an intestinal washout technique and these results were correlated with the radiographic appearance on plain films of the abdomen. The amounts ranged from 30 to 199 ml with an average of 86 ml. The composition of the gas indicates that not all intestinal gas originates from swallowed air. After a minimum of training, three radiologists showed marked improvement in their accuracy at estimating the volume of gas from its radiographic appearance.
