Correlation between PET findings and BMB results
| PET/CT-assessed staging results . | Patients with negative BMB (n = 180), n (%) . | Patients with positive BMB (n = 81), n (%) . | P for difference between groups . |
|---|---|---|---|
| PET/CT stage | <.001 | ||
| I | 70 (38.9) | 4 (4.9) | |
| II | 24 (13.3) | 2 (2.5) | |
| III | 47 (26.1) | 26 (32.1) | |
| IV | 39 (21.7) | 49 (60.5) | |
| Focal BM PET/CT lesions | <.001 | ||
| Unifocal | 8 (4.4) | 8 (9.9) | |
| Bifocal | 10 (5.6) | 6 (7.4) | |
| Multifocal | 12 (6.7) | 25 (30.9) | |
| With diffuse uptake (unifocal or multifocal uptake lesions) | 2 (1.1) | 7 (8.6) | |
| Pure diffuse FDG uptake | 8 (4.4) | 4 (4.9) | |
| No PET/CT lesions | 140 (77.8) | 31 (38.3) |
