Viscover’s innovative ultrasound agent PolySon T consists of microbubbles, which are optimized for imaging of tumors. The agent’s exceptionally high contrast enhancement coupled with its long blood half-life enables improved visualization of vascularized tumors in animal tumor models.

The innovative ultrasound agent, PolySon T:

  • Is highly echogenic delivering optimal contrast at all typically used frequencies
  • Has a long circulation time enabling a wide imaging time window
  • Is suitable for the visualization of vascularized tumors
  • PolySon T is Viscover’s leading US agent for tumor imaging

Apply PolySon T to:

  • Detect tumors in animal tumor models
  • Effectively monitor tumor progression
  • Evaluate the efficacy of new therapies
