Yang et al reported a number of equations for estimating standard liver volume based on a range of data sources. The authors are from Pohang University and Chonbuk National University in South Korea.
Parameters used in all of the 11 equations represented:
(1) age in years
(2) gender (female 0, male 1)
(3) body weight in kilograms
(4) body surface area in square meters (equation not specified)
(5) skeletal muscle mass (SMM) in kg
(6) waist circumference in cm
(7) abdominal fat percentage
(8) body fat percentage
(9) subcutaneous fat area
Equations based on the first 4 parameters are:
standard liver volume in mL=
= (-4.1 * (age)) + (41.6 * (gender)) + (15.3 * (body weight)) + 331
= (-4.3 * (age)) + (16.2 * (body weight)) + 307
= (-4.1 * (age)) + (969 * (BSA)) + 227
= (15.8 * (body weight)) + 136
= (-3.8 * (age)) + (44.9 * (gender)) + (15.7 * (body weight)) + 279
= (-4.16 * (age)) + (16.5 * (body weight)) + 272
with the first equation preferred.
