Table 3 Accuracy of cut-off SUVmax values for mediastinal malignancy, expressed as absolute value or as a ratio
From: FDG-PET parameters predicting mediastinal malignancy in lung cancer
Sensitivity | Specificity | PPV | NPV | Accuracy | |
|---|---|---|---|---|---|
SUVmax mediastinum >4 | 72.3 | 80.4 | 81.0 | 71.4 | 76.0 |
\( \frac{\mathrm{SUVmax}\kern0.5em \mathrm{Mediastinum}}{\mathrm{SUVmax}\kern0.62em \mathrm{Tumor}}>0.4 \) | 70.8 | 73.2 | 75.4 | 68.3 | 71.9 |
