26
Pathophysiology of **Wilson's Disease**
- Decreased biliary excretion of copper - Decreased incorporation of copper into ceruloplasmin

What is a fibroscan?
- Fibro Scan is an imaging-based diagnostic test developed by Echosens that looks at liver fibrosis (stiffness, scarring) and steatosis (fat) using transient- elastography technology. - Fibro Scan can be used on patients in need of staging of their NAFLD/NASH
