Calculate Y90 microsphere activity for treatment planning. It helps determine vial orders based on calendar decay and allows saving and exporting case summaries. Designed for qualified professionals in radioembolization.
What's New in Y90 Dosing
1.2.1
September 18, 2026
The guided tutorial has been rebuilt as four chapters: calculating an activity, choosing a glass vial, choosing a resin vial, and saving a case. Each one walks through the real screens and highlights the control it's describing. This replaces an earlier walkthrough that had fallen out of step with the app — parts of it pointed at a vial grid that has since moved into its own picker. There's also a new launch screen.

What is Y90 Dosing used for?
Y90 Dosing is an educational and verification tool for qualified professionals in radioembolization. It helps calculate Yttrium-90 glass microsphere activity and order vials based on published dosimetry formulations.
What types of microspheres does Y90 Dosing support?
Y90 Dosing specifically supports glass microspheres, such as TheraSphere. It does not support resin microspheres, BSA dosing, voxel or DICOM dosimetry, or overlapping territories.
Can Y90 Dosing be used as a medical device?
No, Y90 Dosing is not a medical device and is not FDA cleared or approved. It is intended for use alongside treatment planning, not in place of it, and all results must be independently verified.
How does Y90 Dosing handle vial ordering?
The app features a vial grid that decays candidate vials from their calibration date to your treatment date and time. This allows you to see the actual delivered activity of a vial on a specific day and time.
What information can be exported from Y90 Dosing?
You can save cases and export a one-page PDF summary. This export includes the treatment plan, vial order details, and all input parameters used to generate the results.
