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.
