Comparison of Acoustic Attenuation Parameter Using FibroTouch With Liver Biopsy for Diagnosis of Hepatic Steatosis

This will be a multi-center, prospective, controlled study. It is expected that about 240 subjects from 10 study centers will be enrolled, and 224 effective subjects will be statistically analyzed in the end, in which 56 effective subjects with stage F0 (25%), 56 effective subjects with stage F1 (25%), 56 effective subjects with stage F2 (25%), 56 effective subjects with stage F3 (25%). By comparison of the result of FibroTouch examination with that of liver biopsy, their specificities, sensitivities and accuracies for diagnosis of liver steatosis will be identified. The patients with liver diseases who need to have a liver biopsy in hospital and meet all of the inclusion criteria and none of the exclusion criteria, may participate in this study. Within two weeks of FibroTouch examination, subjects are required to have qualified histological specimens of liver biopsy for comparation.
