The absorbed dose rate is the admitted dose per time unit.

See Absorbed Dose.

Omnipaque (iohexol) is a nonionic, low-osmolar contrast agent and is also available for oral use, offering gastrointestinal (GI) visualization with minimal side effects. Omnipaque has a neutral taste that even kids will drink.
Orally administered iohexol is poorly absorbed from the normal gastrointestinal tract. Omnipaque is well tolerated and absorbed if leakage into the peritoneal cavity occurs.
The recommended dosage of undiluted Omnipaque (at a concentration of for example 350 mg/mL) for computed tomography of the abdomen in adults is 500 mL to 1000 mL, diluted to concentrations of 6 mg/mL to 9 mg/mL. The oral dose should be administered about 20 to 40 minutes prior to the CT scan.
