Recently published international recommendations for use of SIR-Spheres® Y-90 resin microspheres

  • Newest publication of its kind focused on Dosimetry
  • Fills a major information gap across international clinical communities
  • Supports best practices to treat patients collaboratively in a program-based system to improve patient outcomes
  • Developed by 43 international and multidisciplinary experts, including 23 members of the steering committee

The SIR-Spheres Advantage empowers practitioners by providing programs and tools to implement these consensus recommendations

Recommendation 23: "For selective ablative treatments, it is recommended to consider a higher specific activity, hence a lower number of microspheres." (Strong consensus)


Recommendation 17: "SIRT should be conducted as soon as possible after the simulation [...]" (Strong consensus)


Recommendation 46: "Post-SIRT dosimetry is recommended." (Strong consensus) / R21-22: "A personalized approach using dosimetry (partition model and/or voxel-based) is recommended for activity prescription." (Strong consensus)
