Diagnostic efficiency of the contrast-enhanced ultrasonography (CEUS), elastosonography (SE) and conventional ultrasonography (CUS).
| Se (%) | Sp (%) | PPV (%) | NPV (%) | Ac (%) | AUC (95% CI)* | |
|---|---|---|---|---|---|---|
| CUES | 51.7 | 88.1 | 48.4 | 89.4 | 81.6 | 0.729 (0.653–0.796) |
| SE | 53.8 | 69.4 | 25.5 | 88.6 | 66.9 | 0.616 (0.536–0.692) |
| CUS | 69.0 | 57.5 | 26.0 | 89.5 | 59.5 | 0.608 (0.528–0.685) |
