Abstract
PurposeThe present study developed formulas for estimation of standard liver volume (SLV) with high accuracy for the Korean population.Materials and MethodsSLV estimation formulas were established using gender-balanced and gender-unbalanced measurements of anthropometric variables, body composition variables, and abdominal geometry of healthy Koreans (n=790). Total liver volume excluding blood volume, was measured based on CT volumetry.ResultsSLV estimation formulas as preferred in various conditions of data availability were suggested in the present study. The suggested SLV estimation formulas in the present study were found superior to existing formulas, with an increased accuracy of 4.0–217.5 mL for absolute error and 0.2–18.7% for percentage of absolute error.ConclusionSLV estimation formulas using gender-balanced measurements showed better performance than those using gender-unbalanced measurements. Inclusion of body composition and abdominal geometry variables contributed to improved performance of SLV estimation.
