Table 5 Demonstrate sensitivity and specificity of lesion to background contrast ratio on CE-FLAIR and CE-T1WI by both observers
| Â | AUC (95% CI) | P value | Cut off point | Sensitivity% | Specificity % |
|---|---|---|---|---|---|
Lesion to background contrast ratio on CE-T1WI (First observer) | 0.634 (0.485–0.784) | 0.152 | 0.122 | 63.3 | 58.3 |
Lesion to background contrast ratio on CE-T1WI (second observer) | 0.628 (0.478–0.777) | 0.174 | 0.113 | 61.2 | 50.0 |
Lesion to background contrast ratio on CE-FLAIR (First observer) | 0.661 (0.499–0.823) | 0.086 | 0.2341 | 71.4 | 66.7 |
Lesion to background contrast ratio on CE-FLAIR (second observer) | 0.719 (0.555–0.882) | 0.02* | 0.2341 | 77.6 | 66.7 |
