Table 3 Showed the cutoff ADC value between recurrent breast carcinoma and benign post-operative changes by both observers
From: Detection of recurrent breast carcinoma using unenhanced breast MRI
ADC | AUC (95% CI) | P Value | Cutoff point | Sensitivity (%) | Specificity (%) | PPV (%) | NPV (%) | Accuracy (%) |
|---|---|---|---|---|---|---|---|---|
First observer | 0.899 (0.811–0.986) | < 0.001 | 1.0 | 80.0 | 90.9 | 66.7 | 95.2 | 88.9 |
Second observer | 0.928 (0.858–0.999) | < 0.001 | 1.25 | 80.0 | 88.6 | 61.5 | 95.1 | 87.03 |
