Equations of Yu et al for Predicting Standard Liver Volume in Koreans

 

Patient selection: Korean

 

Parameters:

(1) body weight in kilograms

(2) body height in centimeters

(3) body surface area (BSA) in square meters

(4) age in years

 

liver volume in mL =

= (982.1 * (BSA)) - 226.5

= (267.6 * (((BSA) - 1.652)^2)) + (1132.2 * (BSA)) - 492.3

= 21.585 * ((body weight)^0.732) * ((body height)^0.225)

Cutoff	liver volume in mL =
BSA < 1.2 sq m	(509.2 * (BSA)) + 186.3
BSA >= 1.2 sq m	(1142.1 * (BSA)) - 499.2
age < 18 years	(812.7 * (BSA)) + 24.6
age >= 18 years	(1145.4 * (BSA)) - 506.1

 

Performance - The equations with the best adjusted R^2:

(1) age < 18 years (0.73)

(2) BSA < 1.2 square meter (0.76)

(3) body weight and height (0.59)
