The pictured radiograph was made in the right lateral decubitus position. It is part of a series of radiographs made during an air-contrast (double-contrast) BE examination. A double-contrast examination of the large bowel is performed to see through the bowel to its posterior wall and to visualize any intraluminal (eg, polypoid) lesions or masses. Various body positions are used to redistribute the barium and air. To demonstrate the medial and lateral walls of the bowel, decubitus positions are performed. The radiograph presents a right lateral decubitus position, because the barium has gravitated to the right side (the side of the hepatic flexure). The air rises and delineates the medial side of the ascending colon and the lateral side of the descending colon. The posterior wall of the rectum could be visualized using the ventral decubitus position and a horizontal beam lateral of the rectum.
