Abstract Studies for evaluating the diagnostic performance of two-dimensional Shear-wave Elastography (2D-SWE) in a patient cohort including various liver disorders, remain limited. We aimed to evaluate the validity of 2D-SWE in the diagnosis of advanced liver fibrosis amongst patients with various liver disorders. In this pathology-based study, patients who underwent a liver biopsy for various benign liver diseases were prospectively recruited during the period between February, 2017 and September, 2020. Data of 2D-SWE, Fibrosis-4 Index (FIB-4), and Aspartate Aminotransferase to Platelet Ratio Index (APRI) were simultaneously collected. The cut-off values for predicting advanced fibrosis, i.e. Metavir fibrosis stage ≥ F3, were determined using Receiver Operating Characteristic (ROC) analysis. The diagnostic performance was evaluated and then compared by Area Under the ROC (AUROC). In total, 95 patients were recruited for study analysis. The diagnostic performance of 2D-SWE was significantly superior to that of both FIB-4 (AUROC: 0.88, 95% confidence interval [CI]: 0.80-0.94; vs 0.72, 95%CI: 0.62-0.81; p=0.001) and APRI (AUROC: 0.88, 95%CI: 80-0.94; vs 0.76, 95%CI: 0.66-0.84; p=0.007). With an optimal cutoff value of 9.3 kPa, the sensitivity and specificity were 90.91% and 76.47%, respectively. In subgroup analysis, the AUROC of 2D-SWE was the highest when compared to that of FIB-4 and APRI in patients with chronic hepatitis B, chronic hepatitis C, fatty liver, and concurrent hepatitis. 2D-SWE can therefore be a valid non-invasive method in the detection of advanced liver fibrosis in various liver diseases.

Abstract Background Pediatric patients with liver disease require noninvasive monitoring to evaluate the risk of fibrosis progression. This study aimed to identify the significant factors affecting liver stiffness values using two-dimensional shear-wave elastography (2D-SWE), and determine whether liver stiffness can predict the fibrosis stage of various childhood liver diseases. Methods This study included 30 children (22 boys and 8 girls; mean age, 5.1 ± 6.1 years; range, 7 days–17.9 years) who had undergone biochemical evaluation, 2D-SWE examination, histopathologic analysis of fibrosis grade (F0 to F3), assessment of necroinflammatory activity, and steatosis grading between August 2016 and March 2020. The liver stiffness from 2D-SWE was compared between fibrosis stages using Kruskal–Wallis analysis. Factors that significantly affected liver stiffness were evaluated using univariate and multivariate linear regression analyses. The diagnostic performance was determined from the area under the receiver operating curve (AUC) values of 2D-SWE liver stiffness. Results Liver stiffness at the F0-1, F2, and F3 stages were 7.9, 13.2, and 21.7 kPa, respectively (P < 0.001). Both fibrosis stage and necroinflammatory grade were significantly associated with liver stiffness (P < 0.001 and P = 0.021, respectively). However, in patients with alanine aminotransferase (ALT) levels below 200 IU/L, the only factor affecting liver stiffness was fibrosis stage (P = 0.030). The liver stiffness value could distinguish significant fibrosis (≥ F2) with an AUC of 0.950 (cutoff value, 11.3 kPa) and severe fibrosis (F3 stage) with an AUC of 0.924 (cutoff value, 18.1 kPa). The 2D-SWE values for differentiating significant fibrosis were 10.5 kPa (≥ F2) and 18.1 kPa (F3) in patients with ALT levels below 200 IU/L. Conclusion The liver stiffness values on 2D-SWE can be affected by both fibrosis and necroinflammatory grade and can provide excellent diagnostic performance in evaluating the fibrosis stage in various pediatric liver diseases. However, clinicians should be mindful of potential confounders, such as necroinflammatory activity or transaminase level, when performing 2D-SWE measurements for liver fibrosis staging.

Background: Noninvasive assessment of liver fibrosis has important clinical significance. Different techniques including two-dimensional shear-wave elastography (2D SWE) and real-time tissue elastography (RTE) are reported to be useful for the noninvasive diagnosis of hepatic fibrosis. All these techniques are affected by many factors. How to choose a reasonable method needs further studies. Purpose: This study was conducted to comparatively assess the diagnostic performance of 2D SWE and RTE in patients with Chronic Hepatitis B (CHB) and influence of inflammation on the stiffness values obtained by both techniques, so as to objectively assess the reasonable choice between these 2 elastography techniques for noninvasive assessment of hepatic fibrosis in clinical practice. Materials and Methods: Four-hundred and thirty-seven patients with CHB meeting the inclusion criteria were enrolled in the study. All patients underwent liver stiffness measurements by using 2D SWE and RTE on the same day. Histologic fibrosis was staged and inflammation activity was graded based on the METAVIR scoring system on liver biopsy specimens. Results: The liver stiffness values by using 2D SWE and RTE both increased in parallel with the degree of liver fibrosis and the grade of inflammation. However, the diagnostic efficacy of significant fibrosis and cirrhosis using 2D SWE was significantly higher than that of RTE. The 2D SWE measurement values were statistically different in different alanine aminotransferase (ALT) levels and METAVIR activity grades; however, no statistically significant differences were observed by using RTE. The diagnostic efficacy of 2D SWE significantly varied with elevated ALT levels compared with RTE. Conclusion: 2D SWE was more accurate than RTE in the assessment of significant fibrosis and cirrhosis in patients with CHB. Compared with RTE, the measurement values and diagnostic performance obtained by 2D SWE were prone to be more easily affected by the inflammation fluctuations.

Abstract Purpose To prospectively assess liver fibrosis with two-dimensional shear wave elastography (2D-SWE) in patients with chronic hepatitis B (CHB) and to compare the performance of this modality with that of serum indices using Scheuer scoring from liver biopsies as the reference standard. Materials and Methods 123 patients with CHB underwent 2D-SWE measurements and serological tests between April 2016 and February 2018. The 2D-SWE and serum indices in the diagnosis of liver fibrosis were assessed using receiver operating characteristic (ROC) analyses. Results The areas under ROC (AUCs) for 2D-SWE, aspartate transaminase-to-platelet ratio index, fibrosis index based on the four factors, Forns score, King’s score, FibroIndex, red cell distribution width-to-platelet ratio, Hepascore, type IV collagen, and hyaluronic acid were 0.851, 0.738, 0.701, 0.739, 0.734, 0.711, 0.692, 0.601, 0.640, and 0.522, respectively, in the diagnosis of substantial fibrosis, 0.975, 0.819, 0.792, 0.829, 0.818, 0.807, 0.732, 0.572, 0.676, and 0.544, respectively, in the diagnosis of severe fibrosis, and 0.972, 0.883, 0.862, 0.908, 0.889, 0.918, 0.808, 0.601, 0.807, and 0.775, respectively, in the diagnosis of cirrhosis. The AUCs of 2D-SWE in the diagnosis of substantial fibrosis, severe fibrosis, and cirrhosis were significantly higher than those of the serum indices (p < 0.05). Conclusion 2D-SWE is a reliable noninvasive method for the assessment of liver fibrosis in patients with CHB with better diagnostic performance than that of nine serum fibrosis indices.
