Abstract
Introduction: Knowledge of the size of the liver is an important factor in diagnosingliver disease. Hepatomegaly is a term used to describe a liver that is enlarged beyondits normal dimensions, and ultrasound is often a front line investigation in the suspicionof hepatomegaly. This study sought to develop a reference range for the size of the normalliver using a simple, reliable and valid measurement technique.
Methods: Two ultrasound images of the liver and a blood test were taken from 126participants. Three simple linear measurements were taken from these two images andconverted to a liver volume using a published equation.
Results: The reference range for liver volume in adults without liver pathology wasfound to be 1060–2223 cm3.
Conclusion: This new measurement technique and reference range is simple and easyto perform in the clinical environment. It has the potential to discriminate a liver normal insize to one with hepatomegaly.
