Background  Evaluation of fibrosis stage is important to monitor progression of liver disease and risk of hepatocellular carcinoma (HCC). While liver biopsy is the gold standard, the method is invasive and faces several limitations. The aim of this study was to determine correlations among METAVIR scores and FibroScan, Virtual-Touch tissue quantification (VTQ), fibrosis index based on four factors (FIB-4 index), and Mac-2 binding protein glycosylation isomer (M2BPGi) level, and for examine differences in the reliability of non-invasive methods to evaluate fibrosis.    Methods  We used liver resection specimens from patients with hepatitis C virus (HCV), correlations were assessed between METAVIR scores and non-invasive method. Receiver operating characteristic (ROC) curves were generated to determine the sensitivity, specificity, and cut off values of the methods.    Results  All Patients group: In F0–2 vs F3–4, the areas under the ROC curve (AUC) (0.85) of FibroScan was significantly higher than that (0.67) of FIB-4 index ( p  = 0.002) and that (0.67) of M2BPGi ( p  = 0.001). The AUC (0.83) of VTQ was significantly higher than that (0.67) of FIB-4 index ( p  = 0.01) and that (0.67) of M2BPGi ( p  = 0.002). In F0–3 vs F4, the AUC (0.86) of VTQ was significantly higher than that (0.65) of FIB-4 index ( p  = 0.04). The AUC (0.89) of FibroScan was significantly higher than that (0.65) of FIB-4 index ( p  = 0.002) and that (0.76) of M2BPGi ( p  = 0.02).  Non-SVR group: In F0–2 vs F3–4, the AUC (0.85) of FibroScan was significantly higher than that (0.84) of FIB-4 index ( p  = 0.02) and that (0.73) of M2BPGi ( p  = 0.003). The AUC (0.84) of VTQ was significantly higher than that (0.74) of FIB-4 index ( p  = 0.04). In F0–3 vs F4, the AUC (0.91) of FibroScan was significantly higher than that (0.67) of FIB-4 index ( p  = 0.003) and that (0.78) of M2BPGi ( p  = 0.02). The AUC (0.88) of VTQ was significantly higher than that of FIB-4 index (0.67) and that of M2BPGi (0.78) ( p  = 0.04).    Conclusions  FibroScan and VTQ best reflected the results of hepatic fibrosis diagnosis using liver resection specimens among the four examination methods evaluated.
