Purpose : The purpose is to determine clinical usefulness of liver Share wave elastography in diagnosing liver fibrosis by comparing test results of liver Share wave elastography and liver biopsy.
Subjects and Methods : tests of liver Share wave elastography and liver biopsy have been done on 54 inpatients who carry hepatitis Type B and Type C between the period of September of 2011 and February of 2012. The degrees of liver biopsy was classified according to the levels of liver fibrosis based on METAVIR. The rates of Liver Shear wave elastography were measured three times and their average was compared and analyzed with liver stiffness optimal cutoff value published on the Ultrasound in Medicine & Biology 2011.
Results : Of all the 54 subjects, 20, 37% of them, were in the range of F0-F1 in liver fibrosis through liver biopsy. Those in the range of F2 and F3 were 22, 41% and 7, 13% respectively. The results of comparing rates of liver stiffness with Optimal cutoff value according to the liver fibrosis showed that 19 subjects, 95%, were in the range of F0-F1, 20 subjects, 90% in F2, 6 subjects, 85% in F3 and 3 subjects, 65% in F4 turned out to fit the optimal cutoff value.
Conclusion : Liver Shear wave elastography tests, diagnosing the liver fibrosis, matched more than 90% in the levels of F0∼F1 and F2 liver fibrosis. This is considered to be useufl in early diagnosis of liver fibrosis.
