ae Demonstrates the ROC curve analysis of the diagnostic reliability of MRE technique in the pre-transplant evaluation of the studied LLDs candidates. The MRE was accurately discriminated between absolutely normal and abnormal hepatic tissues by using an optimal cut-off value of liver stiffness value ≥ 2.24 kPa with 0.992 AUC, 98.65% sensitivity, 100% specificity, and 99.24% accuracy (a). Moreover, MRE technique was accurately detected hepatic steatosis of grade ≥ S1a by utilizing a cut-off value of liver stiffness ≥ 2.35 kPa with 0.981 AUC, 96.83% sensitivity, 100% specificity, and 98.10% accuracy, while it detected hepatic steatosis of grade ≥ S1b at a cut-off value of liver stiffness ≥ 2.38 kPa with 0.984 AUC, 96.90% sensitivity, 100% specificity, and 98.44% accuracy (b and c, respectively). Additionally, MRE technique identified fibrosis of grade ≥ F1 by using an optimal cut-off value of liver stiffness ≥ 2.42 kPa with 0.990 AUC, 97.51% sensitivity, 100% specificity, and 99% accuracy, while it detected hepatic fibrosis of grade ≥ F2 by using an optimal cut-off value of liver stiffness ≥ 2.57 kPa with 0.988 AUC, 97.22% sensitivity, 100% specificity, and 98.80% accuracy (d and e, respectively)
