Sensitivity, Specificity, and Accuracy for All Lesions Using 4 Different Combinations of Evaluation Parameters as Input Variables for DA
| Parameter | SUV | FD | SUV, FD | SUV, FD, VB, K1–k4, Ki* |
|---|---|---|---|---|
| Sensitivity (%) | 54.05 (20/37) | 71.88 (23/32) | 64.52 (20/31) | 75.86 (22/29) |
| Specificity (%) | 91.30 (42/46) | 81.58 (31/38) | 88.89 (32/36) | 97.22 (35/36) |
| Accuracy (%) | 74.70 (62/83) | 77.14 (54/70) | 77.61 (52/67) | 87.69 (57/65) |
↵* Combination of evaluation parameters according to Patlak and Blasberg (10).
FD=fractal dimension.
Full kinetic analysis was possible in 29 of 37 tumors and 36 of 46 benign lesions.
