| Bone lesion detection concordance | |||||
| Scan time point | Tracer | 18F-DCFBC only | Concordant | 18F-NaF only | P |
| Baseline | 18F-NaF SUVmax | – | 23.9 (4.72–83.4) | 12.3 (2.82–65.3) | 0.064 |
| 18F-DCFBC(2 h) SUVmax | 5.46 (4.17–6.09) | 6.01 (1.69–50.85) | – | 0.48 | |
| Follow-up | NaF SUVmax | – | 22.7 (5.27–81.8) | 13.2 (4.1–55.5) | 0.006 |

Data are median, with range in parentheses. Lesions stratified by detection on both modalities: DCFBC only, concordant (DCFBC and NaF), and NaF only. Difference in SUVmax across groups assessed using Wilcoxon rank-sum test for clustered data.
