ExiTron U and ExiTron V have been developed as reference contrast agents for maximum convenience.

ExiTron U is a classical monomeric non-ionic extracellular contrast agent for CT angiography (CTA) and is based on the proven iopromide agent that has long been used in human clinical practice.

ExiTron V is the dimeric counterpart to ExiTron U, is based on iodixanol and has been adapted for animal imaging.

ExiTron U and Exitron V, the trusted standards from human clinical CT, allow you to focus on the actual imaging experiment by:

  • Saving you time eliminating tedious dilution and formulation steps
  • Providing the consistent, reliable quality of all Viscover products
  • Serving as a reference contrast agent
  • Discover Viscover's ExiTron agents – reliable CT agents adapted from clinical practice
