Methods of Determining the Size of the Adult Liver Using 2D Ultrasound

Abstract

Sonography is an effective, noninvasive, safe, and inexpensive technique for measurement of the liver. Measurements of the liver using 2D ultrasound aid in diagnosing and tracking liver disease and in surgical planning. Multiple studies have developed techniques to measure the adult liver using 2D ultrasound. The aim of this systematic literature review was to determine whether a correctly developed, reliable, and reproducible technique for measuring the liver using 2D ultrasound has been reported. Analysis of studies meeting the inclusion criteria showed that none of these studies has been rigorously undertaken in terms of sample size justification, validity, reliability, and/or statistical analysis.
