Yang et al reported a formula for estimating standard liver volume in a Korean adult based on simple body measurements. An accurate volume of the liver is important to determine for liver transplantation. The authors are from Handong Global University and Jeonbuk National University in South Korea,
Parameters:
(1) body weight in kilograms
(2) thoracic width in cm (distance from left to right costophrenic angle in AP image)
(3) liver height in mm (differences between the z-coordinates of the top and bottom CT images containing liver, Figure 2)

The authors suggest that the equation may be suitable for Asian populations.
