Point shear wave elastography by acoustic radiation force impulse (ARFI) of rare chronic liver disease such as autoimmune hepatitis (AIH) and overlap-syndrome

Purpose: Acoustic radiation force impulse (ARFI) elastography is a non-invasively method for evaluating liver fibrosis. Performance data on rare autoimmune liver diseases like autoimmune hepatitis (AIH) and overlap-syndrome are sparse. Therefore, ARFI shear wave velocities of the liver were ascertained and correlated with histological degree of fibrosis. Material and methods: In a retrospective analysis, a total of 28 patients (21 female, 7 male, mean age 49 years, range: 19 – 74 years) with AIH (n = 19) and overlap-syndrome (n = 9) have been evaluated by use of ARFI elastography and histological degree of fibro…
