The gastrointestinal tract cannot be reliably studied by MRI without the use of contrast agents. Oral contrast agents may dramatically improve utility of MRI for gastro- diagnostics. The only clinically approved agents for that purpose are soluble iron compounds. (ferrous gluconate, ferric ammonium citrate) and Gd-DTPA. There is a problem with dosage of iron salts, which may not exceed the levels above those when iron supplementation is used. There are no particulate agents approved for oral use yet.
