Single Contrast Barium Enema (cont.)

Conduct of the Examination (cont.)
  1. After changing the spot film, roll the patient into the LPO position.
    • Again, instruct the assistant to partially unclamp the tubing and allow the barium to slowly flow by gravity through the rectosigmoid colon while you pan back and forth with the fluoroscope between the head of the barium column and the sigmoid region.
    • When the sigmoid colon is well filled, take a spot image of the rectosigmoid colon in the LPO position.

    NOTE: Rectosigmoid spot films are obtained early because reflux of barium into the cecum and terminal ileum may later obscure this area.
