X-ray examination allows to see the position and relief of the mucous membrane of the small intestine. The loins of the jejunum are located on the left and in the middle parts of the abdominal cavity, vertically and horizontally. Hairs of the ileum occupy a place in the right lower abdomen, oriented vertically and in an oblique direction. Some loops drop into the small pelvis. The small intestine on the radiographs is visible in the form of a crimped narrow tape 1-2 cm wide, and with a reduced wall tone 2.5-4.0 cm. The intestinal contours are uneven due to circular folds protruding into the lumen of the gills, whose height on the radiographs is 2-3 mm in the jejunum and 1-2 mm in the iliac. With a small amount of radiopaque mass in the luminal cavity ("weak" filling), folds are clearly visible, and with "tight" filling, the size, position, shape and contours of the gut are determined.
