The purpose of this study is to assess the influence of body mass index (BMI) on the accuracy of ultrasound diagnostics of diffuse liver diseases, in particular non-alcoholic fatty liver disease (NAFLD). An analysis of the data of patients with different BMI values was conducted. It has been established that an increase in BMI reduces the diagnostic accuracy of ultrasound due to a deterioration in visualization. The obtained results indicate the need to consider BMI when interpreting ultrasound data.
