Hexabrix is an ionic dimer contrast medium. Intravascular injection of Hexabrix enhances those vessels in the path of the flow, permitting radiographic visualization of the internal structures of the human body until significant hemodilution occurs. The contrast agent is transported through the circulatory system to the kidneys and is excreted unchanged in the urine. Hexabrix is used primarily for peripheral arteriography

Hypaque 76 is a radiopaque contrast agent supplied as a 76 percent sterile aqueous solution providing 66 percent (w/v) diatrizoate meglumine and 10 percent (w/v) diatrizoate sodium.

GE Healthcare has discontinued Hypaque 76 for unknown reasons.

Hypaque Meglumine is an ionic contrast agent. Hypaque Meglumine 60 percent (w/v) is an aqueous solution containing 60 g of the meglumine salt of diatrizoic acid per 100 mL of solution.
The degree of contrast enhancement at computed tomography is directly related to the amount of iodine administered. In adults the amount of iodine usually required for contrast enhancement ranges from 28 to 42 g.
Hypaque Meglumine is also available in concentrations of 18% and 30%.

Isovue® is a nonionic contrast agent with a wide range of iodine concentrations.
Isovue-370 with its highest concentration of contrast approved for CT is an excellent agent to match the speed and power of multi-detector row CT (MDCT). Prefilled syringes provide easy and efficient contrast media handling. Isovue-M® is indicated for CT myelography.

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).
