Y90 Shunt Calculator
Calculate hepatopulmonary shunt percentage for Y90 radioembolization therapy planning
Calculation Method
PACS MethodPACS method uses mean counts and area measurements to calculate total counts.
PACS Method — Input Values

Hepatopulmonary Shunt
0%
Clinical Interpretation
Normal: Hepatopulmonary shunt < 10%
Caution: Shunt 10–20% may require dose modification
Contraindication: Shunt > 20% typically precludes Y90 therapy
