Ultrasound examination of the liver: the search for the most reproducible and easy to operate measuring method of the right lobe oblique craniocaudal diameter

. Mismatching of the organ sizes to the standard measurements is the sign of pathology, so it is important to make measurements using the same method for the same type of assessment. Goal : to evaluate the intra- and inter-research reproducibility of the oblique craniocaudal diameter measurement of the right liver lobe with the application of Russian and European methods by different operators, and find out which of the methods is the most convenient for practical application. Materials and methods . 47 healthy volunteers and 3 operators were participated in the study. One of the operators participated in both stages of study. Results . Keeping conditions such as quiet breathing and longitudinal scanning in the anterior axillary line from the VII-X intercostal spaces increases reproducibility and provides well visualization of the lobe even if the patient is not prepared for the study. Conclusion . The oblique size of the right lobe is highly reproducible for both methods, but the European method (longitudinal scanning of right lobe) is more convenient for the practical application.
