Two methods to assess liver echogenicity were compared.Liver/kidney echogenicity ratio was measured in 41 persons with the ultrasound software and visually graded by two radiologists and a radiographer. These echogenicity ratios and grades were related to risk factors for fatty liver and to liver enzyme levels.These determinants explained 55% of the radiologists' mean grades, 14% of the radiographer's and 31% of the measured echogenicity ratios.Radiologists' visual gradings correlated best with the indirect determinants of early liver pathology. Computerized measurements may be inferior to visual grading due to the lack of holistic tissue diagnostics.
