Abstract
Introduction. Hepatomegaly is the most frequent and easily detectable, sometimes the only chronic liver disease symptom. An objective assessment of liver size with ultrasound is complex.
Aim. To assess the intra- and inter-research reproducibility of ultrasound liver linear measurements.
Materials and methods. To study the reproducibility of liver measurements, each patient was examined by two specialists of ultrasound diagnostics performing 24 liver measurements twice.
Results. The average errors for all left lobe measurements for more experienced doctor vary from 4 to 13,5% and for less experienced — from 5 to 22%. When examining the right lobe, the average errors for both sonographers don’t exceed 10%.
Conclusion. The anteroposterior size of the left lobe and maximum craniocaudal size of the right lobe are the most reproducible. We recommend obtain liver measurements of the right lobe at the anterior axillary line due to the lower bulge of the chest, which allows the transducer to be installed parallel to the sagittal plane.
