"Barium sulfate contrast media have been used for many decades, and are well-established as oral agents for the examination of the GI tract. Their use is generally restricted to radiographic and fluoroscopic examinations. Occasionally they are also used for CT examination of the GI tract (e.g. CT colonography in patients with a history of adverse reaction to iodinated contrast media). They are cheap and well-tolerated by most patients, complications from their use are rare."

"Iodinated contrast media are the mainstay contrast agents for use in radiographic, fluoroscopic, angiographic and CT imaging. They are a versatile group of agents used for intravenous, oral and other routes of administration, such as urethral and intra-articular."
