ExiTron ultra 18000 is an innovative nanoparticulate agent that delivers ultimate contrast in CT angiography studies. It is based on a post-transition metal with strong X-ray attenuation power. The agent’s exceptionally high contrast enhancement coupled with its long blood half-life enables detailed visualization of vascular structures.

This unique nanoparticulate agent for CT angiography:

  • Delivers the highest contrast enhancement of all ExiTron products
  • Enables detailed visualization of vascular structures
  • Highlights regions of increased vascular permeability
  • Provides a long circulation time and a broad acquisition time window
  • ExiTron ultra 18000 is Viscover’s novel high-end agent for CT angiography

Apply ExiTron ultra 18000 to:

  • Visualize the vascular system at unprecedented detail
  • Detect regions of increased vascular permeability
  • Perform spectral photon-counting CT
