Iodinated contrast media are contrast agents that contain iodine atoms used for x-ray-based imaging modalities such as computed tomography (CT). They can also used in fluoroscopy angiography and venography and even occasionally plain radiography. Although the intravenous route of administration is most common they are also administered by many other routes including gastrointestinal (oral
