Table I.
Cortical thickness measurements for both imaging modalities.
| Variable | MRI (mm) | CT (mm) | Difference (mm) | P value | ICC |
|---|---|---|---|---|---|
| Humerus 5 cm | 2.1 [1.8 to 2.3] | 2.3 [2.1 to 2.6] | 0.2 [−0.2 to 0.6] | .727 | 0.92 [0.62 to 0.98] |
| Humerus 10 cm | 3.2 [2.9 to 3.5] | 3.6 [3.3 to 3.9] | 0.4 [ 0.0 to 0.9] | .609 | 0.79 [0.08 to 0.95] |
| Humerus 15 cm | 3.9 [3.4 to 4.4] | 4.2 [3.7 to 4.7] | 0.3 [−0.5 to 1.1] | .766 | 0.92 [0.58 to 0.98] |
| Glenoid | 1.2 [1.0 to 1.3] | 1.0 [0.9 to 1.1] | −0.2 [−0.4 to 0.0] | .255 | 0.48 [−1.29 to 0.88] |
All data are presented as mean [95% confidence intervals]. P values are the results of paired Student’s t tests.
MRI, magnetic resonance imaging; CT, computed tomography; ICC, intraclass correlation coefficient.
