THE VALUE OF SHEAR WAVE ELASTOGRAPHY IN THE COMPLEX DIAGNOSIS OF CHRONIC VIRAL HEPATITIS C

Abstract

The diagnostic capabilities of ultrasound elastography in the twodimensional shear wave (2D SWE) mode were studied in 120 patients with chronic  viral hepatitis C. The control group consisted of 40 healthy volunteers with a body mass index of 24-27 without clinical, virological changes. It has been shown that
2D SWE ultrasound is an integral part of gray-scale, doppler studies in the system of standard examination of patients with CVHC and can provide valuable additional qualitative and quantitative information about the degree of development of the process in the liver. It was shown that in the stage of fibrosis F1 according to METAVIR, the liver stiffness indices are 6.2 kPa, and the shear wave velocity is 1.3±0.2 m/sec. With the further development of fibrosis F2-
F4, these indicators increase, respectively,from 6.3 kPa to 30.3 kPa, and the shear wave velocity up to 2.3±0.3 m/sec. in the F4 stage according to METAVIR. The results of 2D SWE elastography make a significant contribution to the timely detection of the degree of fibrosis development in Chronic viral hepatitis C.
