Equation of Urata et al for Estimating Liver Volume Based on Body Surface Area (BSA)

Urata et al developed an equation for estimating liver volume based on body surface area (BSA). The authors are from Shinshu University in Japan.

Parameters:

(1) liver volume in mL

(2) body surface area in square meters

estimated liver volume in mL =

= (706.2 * (BSA)) + 2.4

where:

• The average density of the liver is 1.060, but this can vary considerably based on the amount of fatty change and/or fibrosis present.
