Newsome et al. recently evaluated a novel elastography-based scoring system (FAST score) using VCTE to identify patients with active NASH (NASH ≥ 4) and significant fibrosis (F ≥ 2)22. The score is calculated from LSM, CAP and AST. At a cut-off of 0.35, the score achieved a sensitivity of ≥ 0.90 for the diagnosis of NASH, a cut-off of 0.67 had a specificity ≥ 0.9022. For the present study, FAST score values were retrospectively calculated by the manufacturer of the VCTE device (Echosens, Paris, France).
