Detection of liver fibrosis and steatosis at early stages is a difficult task for clinical practice, due to the lack of early signs in routine radiation diagnostics. Aim. To evaluate the efficacy of ultrasound shear elastography and ultrasound steatometry of the liver with the use of domestic ultrasonic diagnostic system Angiodin-Sono/N-Ultra. Materials and methods. 264 people held ultrasound elastography and ultrasound steatometry. 38 patients underwent percutaneous puncture liver biopsy and subsequent pathophysiological examination. Results. High correlation of fibrosis obtained at the Angiodin-Sono/N-Ultra and the leading ultrasonic systems with shear elastography was revealed. Cross-sectional comparative analysis of elasticity with the results of liver steatometry was conducted. Conclusions. Results obtained in all groups correlate with the data obtained in studies on Fibroscan. When working with system Angiodin we got a simultaneous comparative analysis of elasticity with the results of liver steatosis. Results appear to be much more stable and compact than those obtained in studies on the Fibroscan. A new diagnostic criterion was revealed the phenomenon of independence of fibrosis and steatosis indices.
