About

These nuclear medicine calculators are adapted from validated NYU protocols and are designed for clinical use in nuclear medicine departments.

Y90 Calculator

Based on the established geometric mean method for calculating hepatopulmonary shunt percentage prior to Y90 radioembolization therapy.

Gastric Emptying

Incorporates proper decay correction factors and provides normal reference ranges for both solid and liquid gastric emptying studies.
