Common MicroCT Contrast Agents

Iodine-based agents such as Isovue and Omnipaque. These contrast agents are used in humans primarily for visualizing vasculature and urinary tract, but may be useful for imaging other organs as well. They are small molecules, rapidly excreted through the kidneys, providing intense contrast in the kidneys and bladder. They can be dosed IP as a way to create contrast outside of organs such as the liver to aid in tumor identification. Both Isovue and Omnipaque come in a formulation ready for injection and are quite cheap (about a dollar per dose). They can be purchased via the punch out vendor McKesson Corporation.
