Liver volumes were measured using computed tomography. Correlations between liver volume and BW, body height (BH), and body surface area (BSA) were analyzed.

The volume grows from a median of 139 ml (111.5\u2013153.6 in newborn) to 1180.5 ml (1043\u20131303.1 at 16\u201318 years). Liver volume was significantly correlated with BW (<jats:italic>r<\/jats:italic> = 0.95, <jats:italic>P<\/jats:italic> &amp;lt; 0.001), BH (<jats:italic>r<\/jats:italic> = 0.92, <jats:italic>P<\/jats:italic> &amp;lt; 0.001), and BSA (<jats:italic>r<\/jats:italic> = 0.96, <jats:italic>P<\/jats:italic> &amp;lt; 0.001). The effect of sex on liver volume increases with BW, and BW of 20 kg was identified as the optimal cutoff value.
