Cheetah® is a barium sulfate suspension for use as an aid for computed tomography of the gastrointestinal tract. The contrast medium contains additional pineapple-banana flavor suspending agents, simethicone, potassium sorbate, citric acid, sorbitol, artificial sweetener and water. Individual technique will determine the suspension quantity and specific procedure used. For computed tomography of the upper gastrointestinal tract should the patient drink 200-300 mL Cheetah® approximately 30-45 minutes before and an additional 200-300 mL approximately 5-10 minutes prior to the CT scan.
For total bowel opacification an additional 250-450 mL dose of Cheetah® may be given the evening before the examination. Approximately 1-2 hours before the examination should the patient drink 250-450 mL and 5-10 minutes before the CT scan another 250-450 mL. If rapid transit is desired, the suspension can be administered chilled. Rectally use of the contrast agent should be at room temperature to body temperature.
