The only contrast agents with single particle sensitivity

Viscover PolySon H and PolySon L ultrasound agents are unique hard-shell ultrasound microbubbles with ideal physiological and contrast properties for all typical ultrasound methods.

Highly echogenic single particle sensitivity for detailed imaging

PolySon agents are micrometer-sized air-filled polymeric particles, or microbubbles. Comprised of a stabile inert organic polymer, they enable reliable in vivo single bubble quantitation via "bubble-destructive" methods, even at high frequencies.

Developed for demanding pre-clinical applications

  • PolySon L is a hard-shell ultrasound microbubble agent, optimal for organ perfusion measurements and the visualization of liver and spleen
  • PolySon H offers you the same capabilities as PolySon L, but is optimized for measurements at the body surface with high acoustic pressures
