Patients who are scheduled by their health care provider for routine computed tomography (CT) scan will be asked to participate in this study. The primary purpose is to determine if there is a difference in patient preference for Omnipaque versus Gastroview as oral contrast for abdominal pelvic CT. A secondary objective is to evaluate if there is significant difference in bowel opacification for the two agents.

Primary Outcome Measures:
  • Preferred Contrast Agent [ Time Frame: 1 Day ] [ Designated as safety issue: No ]
    The primary outcome variable is the taste test when subjects will be asked which preparation they prefer. Possible answers include Onmipaque, Gastroview or neither.

Secondary Outcome Measures:
  • Bowel Opacification Score [ Time Frame: Collected day of study ] [ Designated as safety issue: No ]
    The bowel opacification score was calculated by adding values for stomach, duodenum, jejunum and ileum for each patient. They were averaged across two doctors who read the studies. Scores can range from 0 (no opacification) to 3 (excellent) for each segment and from 0 to 12 for bowel opacification score.
