Introduction: ARFI is a new technique that uses acoustic push pulse to generate tissue displacement resulting in shear wave propagation, can be used to measure elasticity of tissue. We aim to assess feasibility of ARFI as a non-invasive method to measure liver fibrosis compared to histological fibrosis scores and to compare our results with the published pooled-meta-analysis cut off values. Material and methods: Prospective study to compare median velocities of ARFI shear wave measurements (Virtual Touch Imaging™ ACUSON S2000, Siemens, Mountain View CA) with Batts and Ludwig liver fibrosis scoring system F0-F4. Results: 70 patients (mean = 49 years) were included. Etiologies were chronic hepatitis C (n = 43), chronic hepatitis B (n = 7) and others (n = 20). Conclusion: ARFI has strong correlation with higher fibrosis scores compared to lower. When compared to the pooled meta-analysis cut off values, the sensitivity and specificity for detecting true F > 3 are higher than that of F > 2.
