According to guidelines published by AASLD, treatment of
underlying disease should be considered if patients with
significant hepatic fibrosis (fibrosis stage 2).
Long-term therapy might result in a regression of
fibrosis. Therefore, differentiating between mild
fibrosis (fibrosis stage 1) and significant fibrosis
is very important to establish an effective treatment
strategy. Our results show that MR elastography had
better diagnostic value than acoustic radiation force
impulse (ARFI) ultrasonography in differentiating mild
fibrosis from significant fibrosis. In conclusion, MRE
provided higher diagnostic performance than ARFI in
differentiating significant hepatic fibrosis (stage
F2) from mild fibrosis.
