Estimation of Standard Liver Volume Using CT Volume, Body Composition, and Abdominal Geometry Measurements

다국어 초록 (Multilingual Abstract)

Purpose: The present study developed formulas for estimation of standard liver volume (SLV) with high accuracy for the Koreanpopulation.
Materials and Methods: SLV estimation formulas were established using gender-balanced and gender-unbalanced measurementsof anthropometric variables, body composition variables, and abdominal geometry of healthy Koreans (n=790). Total livervolume excluding blood volume, was measured based on CT volumetry.
Results: SLV estimation formulas as preferred in various conditions of data availability were suggested in the present study. Thesuggested SLV estimation formulas in the present study were found superior to existing formulas, with an increased accuracy of4.0−217.5 mL for absolute error and 0.2−18.7% for percentage of absolute error.
Conclusion: SLV 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 performanceof SLV estimation.
