Coarsely echogenic liver. ARFI value of 3.4.
Focal lesion in the left lobe.
Acoustic Radiation Force Impulse (ARFI):
ARFI reference values: <1.35 - absent or mild fibrosis (F0 or F1) 1.35-1.55 - significant fibrosis (F2) 1.55- 1.80 - severe fibrosis (F3) >1.80 - cirrhosis (F4) These thresholds are not absolute. Based on metanalysis of pooled data which included a predominance of HCV patients - Friedrich-Rust et al J Viral hepatitis 2012, 19 e212-1219 Results should be interpreted in clinical context. Such things as inflammatory activity & venous congestion can elevate the ARFI value.
