The size of the liver in children can be correlated with body length. Ultrasound measurements can be used to estimate liver size for comparison with population norms. The study was done at the Universities of Mainz and Freiburg in the Germany.
Ages of subjects: from 10 days to 17.6 years
Sonography:
(1) The patients are measured in the supine position.
(2) Section planes were taken in the longitudinal axis along the anterior axillary, medioclavicular, and sternal lines.
index of liver size =
= 0.2618 (((extent along the anterior axillary line in cm)^2) + ((extent along the medioclavicular line in cm)^2) + ((extent along the sternal line in cm)^2))
regression line for the mean index of liver size =
= (0.53 * (body height in cm)) – 8.97
95% limits: +/- 21.25
