Real time shear wave elastography in chronic liver diseases: Accuracy for predicting liver fibrosis, in comparison with serum markers

Figure 1 Score values of liver stiffness by according to fibrosis stage (n = 70). Boxplots summarize the liver stiffness by shear wave elastography (SWE) for each fibrosis classification. For each box, the box gives the interquartile range, that is, the 25^th to 75^th percentiles of liver stiffness by SWE, with line inside the box denoting the median, the 50^th percentile of data. Statistical significant test was done by Tukey test using ranks.

Figure 2 Receiver-operating characteristic curves of liver stiffness determined by shear wave elastography for diagnosis of significant fibrosis (F0-1 vs F2-4, A), advanced fibrosis (F0-2 vs F3-4, B) and cirrhosis (F0-3 vs F4, C) (n = 70).

Figure 3 Receiver operating characteristic curves of noninvasive serum markers for discriminating F0-1 vs F2-4 (significant fibrosis, A), F0-2 vs F3-4 (advanced fibrosis, B) and F0-3 vs F4 (cirrhosis, C) (n = 61). SWE: Shear wave elastography; APRI: Aspartate aminotransferase to platelet ratio index.

Figure 4 Comparison of receiver-operating characteristiccurves of noninvasive serum markers for discriminating F0F1 vs F2-4 (significant fibrosis, A) and F0-2 vs F3F4 (advanced fibrosis, B) in 36 patients with chronic viral hepatitis. ROC: Receiver-operating characteristic curves; SWE: Shear wave elastography; APRI: Aspartate aminotransferase to platelet ratio index.

Figure 5 Comparison of receiver-operating characteristic curves of noninvasive marker for discriminating F0F1 vs F2-4 (significant fibrosis, A) and F0-2 vs F3F4 (advanced fibrosis, B) in 25 patients with non-viral chronic liver diseases. ROC: Receiver-operating characteristic curves; SWE: Shear wave elastography; APRI: Aspartate aminotransferase to platelet ratio index.
