Acoustic radiation force impulse elastography for non-invasive assessment of disease stage in patients with primary biliary cirrhosis: A preliminary study

Aim To investigate the diagnostic performance of the acoustic radiation force impulse (ARFI) elastography for the assessment of primary biliary cirrhosis (PBC) stage. Materials and methods Sixty-one patients with PBC in which liver biopsy and ARFI elastography measurements were performed in the same session were included in the study. The diagnostic performance of ARFI elastography for predicting the PBC stage was determined from the area under receiver operating characteristics (AUROC) curve analysis. Results ARFI elastography correlated significantly with histological stage ( r  = 0.74, p Conclusion ARFI elastography is an acceptable and powerful technique for quantitative assessment of PBC stage.
