Is ARFI elastography reliable for predicting fibrosis severity in chronic HCV hepatitis?

Figure 1 Correlation between liver stiffness evaluated by acoustic radiation force impulse and the severity of fibrosis assessed according to the Metavir scoring system. ARFI: Acoustic radiation force impulse.

Figure 2 Predictive value of liver stiffness measurements by acoustic radiation force impulse. A: The presence of fibrosis (F ≥ 1 Metavir); B: The presence of significant fibrosis (F ≥ 2 Metavir); C: The presence of severe fibrosis (F ≥ 3 Metavir); D: The presence of cirrhosis (F = 4 Metavir).
