It functions as a contrast agent by opacifying blood vessels in the path of flow of the contrast agent, permitting radiographic visualization of the internal structures until significant hemodilution occurs.  Available as the FDA-approved product Ultravist, iopromide is used in radiographic studies such as intra-arterial digital subtraction angiography (IA-DSA), cerebral and peripheral arteriography, peripheral venography, excretory urography, brain computer tomography (CT), coronary arteriography, left ventriculography, visceral angiography, and aortography."}]
