Solid Organ Volume Calculator

Select the organ of interest below to calculate the volume based on imaging findings.

Which organ do you want to calculate volume of?
Type of gonad

CT/MRI measurements

US measurements

Expected Liver Volume based on Height and Weight

Select measurement units
Optional, for calculation of PSA density
Most references recommend using the ellipsoid volume measurement. Although, some references recommend using the bullet volume measurement for glands smaller than 55ml.

Splenic volume and index

Only required for calculation of the Splenic volume based on the revised formula for ultrasonographic measurements.

Expected upper limits of normal for splenic length and volume

Patient's Sex
Only valid for heights >150cm
