ELF –> enhanced liver fibrosismeasures 3 markers to grade severity of cirrhosis

260
Q

USS appearance in fibrosis

A
  • Nodularity of the surface of the liver- “corkscrew” appearance to the arteries with increased flow as they compensate for reduced portal flow- Enlarged portal vein with reduced flow- Ascites- Splenomegaly
261
Q

262
Q

Those considered high risk for liver fibrosis
