Linear Correlations Between SUV and Synovial Thickness on US
| Joints (n) | Location of US scanning | r | P |
|---|---|---|---|
| All (356) | 0.56 | <0.0001 | |
| Knees (42) | Lateral patellar recess | 0.56 | <0.0001 |
| Suprapatellar recess | 0.78 | <0.0001 | |
| Medial patellar recess | 0.73 | <0.0001 | |
| Sum | 0.80 | <0.0001 | |
| Wrists (25) | Radiocarpal (top of lunate) | 0.44 | 0.02 |
| Intercarpal (top of capitate) | 0.40 | 0.04 | |
| Sum | 0.50 | 0.01 | |
| MCP (129) | Dorsal surface | 0.50 | <0.0001 |
| PIP (128) | Dorsal surface | 0.39 | <0.0001 |
| Ankles (16) | Top of talar neck | 0.64 | 0.008 |
| MTP-1 (16) | Dorsal surface | 0.36 | 0.2 |
Sum = combined thickness resulting from multiple scans (3 sites for knees and 2 sites for wrists).
P values ≤ 0.05 are significant.
