How Strongly Do Physical Examination Estimates and Ultrasonographic Measurements of Liver Size Correlate? A Prospective Study

Liver size assessed by physical examination and ultrasound has long been used to gain useful clinical information. The size measurements obtained by these modalities have been difficult to compare as they are measured in 2 different axes (transaxial vs midclavicular). Our objective was to identify a measurement correlation between ultrasound and physical examination liver size findings. We aimed to develop a correction factor whereby the liver size could be translated between the measured transaxial size obtained by ultrasound and physical examination size when measured in the midclavicular line.
