PolySon agents have been optimized for organ perfusion measurements and visualization of the liver and spleen. They are the only agents available that are suited for stimulated acoustic emission imaging (SAE) based on inducible bubble rupture.

PolySon, the unique hard-shell ultrasound microbubbles:

  • Are highly echogenic at all typically used frequencies
  • Deliver optimal contrast in all typical ultrasound methods, even above 30 MHz
  • Visualize organ perfusion at HF ultrasound microscopic resolutions
  • Apply Viscover's leading ultrasound contrast agents for organ perfusion
  • Benefit from the only ultrasound contrast agents on the market with added capabilities for stimulated acoustic emission (SAE/SPAQ) methods
Physico-chemical properties and structure
PolySon H:

Optimized for high acoustic pressures

PolySon L:

All purpose and recommended for low acoustic pressure methods, e.g. organ perfusion

Particle size (number-weighted):

1-3 µm

PolySon liver SAE imaging and heart perfusion

Left: Liver imaging based on stimulated acousting emission using PolySon H. The pseudo-doppler effect resulting from the rupture of single bubbles can be seen in red and blue false-color.

Right: Heart perfusion in mouse using PolySon L. The three frames from the video clip show the filling of the heart with contrast agent in green false-color.
