MD-Gastroview® (solution of 660 mg diatrizoate meglumine and 100 mg diatrizoate sodium Solution) is an iodinated oral contrast agent with lemon-vanilla-flavor. MD-Gastroview® is water-soluble and suitable for oral or rectal administration.
MD-Gastroview® is indicated for radiographic and CT examination of the esophagus, stomach, proximal small intestine and colon, when a barium sulfate suspension is not feasible or contraindicated.
A usual adult dose for abdominal CT is 240 mL of a solution prepared by diluting 25 mL (9.17 g iodine) to one liter with tap water. Less dilute solutions [up to 77 mL (28.26 g iodine) diluted to one liter with tap water] may be used when indicated. The dose is administered orally about 15 to 30 minutes prior to imaging in order to permit the contrast medium to reach the pelvic loops.

Optiray® is a radiographic contrast agent. Optiray® is available in concentrations from 160 to 350 mg/mL organically bound iodine. Optiray® solutions have osmolalities 1.2 to 2.8 times that of plasma (285 mOsm/kg water).
Optiray® 160 is recommended for intraarterial digital subtraction angiography (IA-DSA).
