Utility of Longitudinal Measurement of the Liver With Ultrasound in Comparison to Computed Tomography Liver Volume in Assessing Hepatomegaly.

The purpose of the study is to retrospectively compare the longitudinal measurement of the liver on ultrasound (US) with liver volume as measured on computed tomography (CT). This institutional review board-approved retrospective study with prospective image analysis included adult patients with US examinations of the liver and CT examinations of the abdomen performed within 2 weeks of each other from January 1, 2010, to April 30, 2016. We recorded the dome-to-tip longitudinal length measurement of the right lobe of the liver on the US study.
