Hepatic fibrosis and supersonic shear imaging in patients with different etiological chronic hepatic diseases

Area of Science:

• Hepatology
• Medical Imaging
• Diagnostic Techniques

Background:

• Chronic liver diseases (CLDs) encompass various etiologies, including viral hepatitis, autoimmune conditions, and metabolic disorders.
• Accurate staging of hepatic fibrosis is crucial for patient management and treatment decisions.
• Non-invasive imaging techniques are increasingly sought to complement or replace liver biopsy.

Purpose of the Study:

• To evaluate the efficacy of Supersonic Shear Imaging (SSI) in distinguishing hepatic fibrosis between different etiologies of chronic liver disease.
• To assess the correlation between SSI-derived shear moduli and fibrosis stages (S0-S4) in patients with chronic hepatitis B, autoimmune hepatitis, and fatty hepatitis.

Main Methods:

• Retrospective analysis of patients diagnosed with chronic hepatitis.
• Diagnosis and fibrosis staging confirmed by shear wave elastography and percutaneous liver biopsy.
• Quantitative analysis of shear moduli values obtained through SSI across different fibrosis stages and etiological groups.

Main Results:

• Significant differences in shear moduli were observed across fibrosis stages (S0-S4) for all studied etiologies.
• Shear moduli generally increased with advancing fibrosis stages in chronic hepatitis B, autoimmune hepatitis, and fatty hepatitis.
• SSI demonstrated the capability to measure varying degrees of liver stiffness indicative of fibrosis in diverse chronic liver disease contexts.

Conclusions:

• Supersonic Shear Imaging (SSI) is a valuable tool for assessing hepatic fibrosis in patients with different chronic liver diseases.
• SSI can differentiate fibrosis severity based on etiological factors, offering a non-invasive alternative for liver assessment.
• The findings support the use of SSI in clinical practice for monitoring liver fibrosis progression and guiding therapeutic strategies.
