Bowel opacification using "Telebrix 38" for CT scanning.

Prior to abdominal and pelvic computed tomographic (CT) scans in children, bowel opacification was performed with dilute sodium ioxitalamate, meglumine and sodium diatrizoate, or barium sulfate. CT scans of 112 patients using one of these contrast agents were reviewed to compare "image quality." We have obtained the best organ and tissue definition when dilute sodium ioxitalamate was utilized to opacify the gastrointestinal tract.
