Model for liver hardness using two-dimensional shear wave elastography, durometer, and preoperative biomarkers

Figure 1 Measurement of liver hardness using a durometer. Durometer placed perpendicular to the liver surface, avoiding underlying tumors or large vessels.

Figure 2 Correlation between liver stiffness and durometer scale. Pearson rank correlation coefficient R² values for stiffness-to-durometer is 0.491, P < 0.001.

Figure 3 Receiver operating characteristic curve for post-hepatectomy liver failure. A: Derivation cohort (n = 74); B: Validation cohort (n = 162). The area under receiver operating characteristic curve of hardness scale in A and B are 0.785, P = 0.005, and 0.765, P < 0.001, respectively. 2D-SWE: Two-dimensional shear wave elastography.
