Combi-elastography Assessment of Chronic Liver Disease Multi-center Study

Combi-elastography Assessment of Chronic Liver Disease Multi-center Study

HITACH developed a new combi-elastography imaging technology combines shear wave imaging and strain imaging technology. In the study, not only the F index which is related to the stage of liver fibrosis can be obtained, but also the A index which is related to the stage of hepatitis can be obtained, which can not be obtained by other ultrasound devices.

HITACHI developed a new combi-elastography imaging technology combines shear wave imaging and strain imaging technology to make full use of these two imaging modalities and make full use of different physical characteristics for imaging and quantitative analysis.

In the study, not only the F index which is related to the stage of liver fibrosis can be obtained, but also the A index which is related to the stage of hepatitis can be obtained, which can not be obtained by other ultrasound devices.

This technology is non-invasive, painless, simple and reliable, therefore it is bound to contribute to the early diagnosis of chronic liver disease and the real-time evaluation in the treatment process, which will play an important role in the clinical application.

Inclusion Criteria:

• Patients with chronic hepatitis B:18-80 years old, no gender limit;Patient with chronic hepatitis B was diagnosed by liver histopathological examination;The pathological examination of liver tissue clearly provides G/S classification information. If there is steatosis, classification information is required;Patients without prehepatic ascites;Sign informed consent.
• Patients with MAFLD:18-80 years old, no gender limit;Meet the diagnostic criteria for metabolic-related fatty liver disease:Liver histological examination has liver steatosis,and meet one of the following three criteria,that is, overweight/obesity,type 2 diabetes (T2DM) or abnormal metabolism;Liver histopathological examination provides information on the classification of liver cell steatosis, fibrosis, and inflammation clearly;Patients without prehepatic ascites;Sign informed consent;
• Patients with DILI:18-80 years old, no gender limit;Patients with drug-induced liver injury was diagnosed by liver histological examination;The pathological examination of liver tissue provides G/S classification information clearly,If there is liver cell steatosis, classification information is required;Patients without prehepatic ascites;Sign informed consent;
• Healthy volunteers:Aged 18 to 60,Gender not limited,BMI<25;No abnormal signs by clinical examination,no fatty liver, No history of chronic liver disease such as hepatitis and liver cirrhosis, no serious gastrointestinal disease;Without metabolic syndrome;There is no history of long-term medication,do not taking any drugs before a month when checking;Did not find the primary lesions of liver, laboratory examination and clinical diagnosis without any liver disease and liver function is normal;Sign the informed consent.
