Study Description
Brief Summary
This study is aimed to compare the results and operating characteristics of liver stiffness measurement with the use of Fibroscan (EchoSens, France) and iLivTouch (Wuxi Hisky Medical Technologies Co., China) in patients with chronic liver diseases.

Detailed Description
This is prospective comparative trial to assess diagnostic characteristics of non-invasive methods of liver fibrosis and steatosis assessment based on the measurement of liver stiffness. The null hypothesis is that novel device, iLivTouch FT100/FT200 and standard probe allows to obtain similar results of liver stiffness and controlled attenuation parameter compared to FibroScan 530 and probes M+ and XL+ in patients with chronic liver diseases. According to the study protocol, standard examination will be performed to eligible subjects on the same day with the use of both devices. At least 10 measurements will be performed with the use of each device to each subject after overnight fasting. The medians of liver stiffness and controlled attenuation parameter measurements, their interquartile range, success rate of measurements and related interpretations of the results (grades of liver fibrosis and steatosis) will be compared. To assess the variability of the results, demographic data (age, biological sex, ethnicity) will be collected; weight and height of the subjects will be measured on the day of examination. Medical history of the subjects will be examined to extract data, confirming the presence of chronic liver diseases and ensure eligibility.

Outcome Measures
Primary Outcome Measures
- Liver stiffness [Study day 1]
Single assessment (Median by at least 10 measurements) of the liver stiffness in kilo pascals will be performed during examination of the subject
- Controlled attenuation parameter [Study day 1]
Single assessment (Median by at least 10 measurements) of the controlled attenuation parameter in kilo pascals will be performed during examination of the subject
Secondary Outcome Measures
- Interquartile range of liver stiffness [Study day 1]
Single assessment (interquartile range by at least 10 measurements) of the liver stiffness in kilo pascals will be performed during examination of the subject
- Interquartile range of the controlled attenuation parameter [Study day 1]
Single assessment of interquartile range of the controlled attenuation parameter (by at least 10 measurements) in kilo pascals will be performed during examination of the subject
- Success rate [Study day 1]
Success rate (a quotient of division of number of successful measurement on the total of number of measurements performed during examination of a subject) with iLivTouch and Fibroscan
- Stage of liver fibrosis [Study day 1]
stage of liver fibrosis according to the liver stiffness and manufacturers instruction on the interpretation of the results of iLivTouch and FibroScan
- Stage of steatosis of the liver [Study day 1]
stage of liver fibrosis according to the measurement of the controlled attenuation parameter obtained during examination of a subject and manufacturers instruction on the interpretation of the results of iLivTouch and FibroScan
