| Summary: | <b>Background:</b> The aim of this study was to investigate the accuracy in fibrosis staging of a novel shear wave elastography (SWE) device (S-Shearwave Imaging by Samsung) and a previously validated 2D-SWE by Supersonic Imagine (SSI) in patients with biopsy proven metabolic dysfunction-associated steatotic liver disease (MASLD). <b>Methods:</b> This prospective study included 75 consecutive patients with MASLD who underwent liver biopsy for suspected MASH. All patients underwent S-Shearwave Imaging by Samsung and 2D-SWE with SSI on the same day of liver biopsy. Fibrosis was histologically assessed using the METAVIR classification system. Agreement between the equipment was assessed with the Pearson coefficient. A receiver operator characteristic curve (ROC) analysis with the Youden index was used to establish thresholds for fibrosis staging. <b>Results:</b> A good correlation was found between S-Shearwave Imaging by Samsung and 2D-SWE with SSI (Pearson’s R = 0.68; <i>p</i> < 0.01). At multivariate regression analysis, S-Shearwave Imaging was associated with advanced fibrosis (≥F3) independently from age, diabetes and platelets (OR 2.94, CI 1.69–5.11, <i>p</i> < 0.01). The fibrosis diagnostic accuracy of both S-Shearwave Imaging and 2D-SWE was good to optimal with AUROCs of 0.81 and 0.70 for significant fibrosis (≥F2), 0.94 and 0.91 for severe fibrosis (≥F3), respectively. The accuracy of S-Shearwave is not significantly different from Fibroscan and Agile3+ (DeLong test <i>p</i> value 0.16 and 0.15, respectively) while is slightly better than 2D-SWE, FIB4 and NFS (DeLong test <i>p</i> value < 0.05). For S-Shearwave Imaging by Samsung, the best cut-off values for diagnosing fibrosis ≥F2, ≥F3 were, respectively, 7.9 kPa (Sens 74.4%, Spec 87.5%) and 8.1 kPa (Sens 95.6%, Spec 78.8%). For 2D-SWE by SSI, the best cut-off values for diagnosing fibrosis ≥F2, ≥F3 were, respectively, 7.2 kPa (Sens 55.8%, Spec 84.4%) and 7.6 kPa (Sens 82.6%, Spec 84.6%). <b>Conclusion:</b> S-Shearwave Imaging is a useful and reliable non-invasive technique for staging liver fibrosis in patients with MASLD. Its diagnostic accuracy is non-inferior to other shear wave elastography techniques (TE and 2D-SWE by SSI). |
