Diagnostic Accuracy of Apparent Diffusion Coefficient Values in 88 Subjects Across METAVIR Stages
| METAVIR | AUROC | ADC* cutoff | Correctly Classified | Sensitivity | Specificity | LR+ | LR− |
|---|---|---|---|---|---|---|---|
| F0 vs. F > 0 | 0.79 | > = 1.51 | 77.3% | 75.8% | 78.2% | 3.5 | 0.3 |
| F ≤ 1 vs. F > 1 | 0.77 | > = 1.33 | 79.6% | 84.9% | 71.4% | 3.0 | 0.2 |
| F ≤ 2 vs. F > 2 | 0.77 | > = 1.31 | 79.6% | 87.3% | 63.6% | 2.6 | 0.2 |
| F ≤ 3 vs. F4 | 0.78 | > = 1.30 | 79.6% | 86.9% | 63.0% | 2.4 | 0.2 |
ADC values are given in × 10−3 mm2/second.
ADC indicates apparent diffusion coefficient; LR+, positive likelihood ratio; LR−, negative likelihood ratio.
