RADIOPAQUE CONTRAST AGENT

A radiopaque composition is provided that includes an inorganic opacifying agent distributed through an aqueous gelatinous substance in an aqueous solvent. A process for making a radiodense vascular fill composition includes adding a gelatinous substance to an aqueous solution. An inorganic opacifying agent suspension is formed in a saline solution or water. The inorganic opacifying agent and gelatin are mixed with water or saline. A process of imaging a vascular system of a subject includes placing a subject under anesthesia or sedation and exsanguinating the subject. An isotonic fluid is then flushed through the vascular system and the radiopaque composition is infused into the subject circulatory system at a temperature of 40 degrees Celsius or greater. After waiting a given time interval for the radiopaque composition to cool and form a solid gel, an imaging scan is performed on the subject.
