Randomized Controlled Trial Clinical Trial
Evaluation of simethicone-coated cellulose as a negative oral contrast agent for abdominal CT.
Because of the increased clinical use of computed tomography (CT) for imaging the abdominal vasculature and urinary tract, there is a need for negative contrast agents. The authors undertook this study to assess the suitability of simethicone-coated cellulose (SCC), which is approved for use as an oral contrast agent in sonography, for use as a negative oral contrast agent in abdominal CT. ⋯ SCC is effective as a negative oral contrast agent for small bowel marking at CT.
