Table II.
Cancellous signal measurements for both imaging modalities.
| Variable | MRI | CT | Correlation | P value |
|---|---|---|---|---|
| Center of the head | 1.18 [1.10 to 1.26] | 106 [ 51 to 160] | −0.087 | .823 |
| Subtuberosity | 1.15 [1.04 to 1.26] | 91 [ 66 to 116] | −0.511 | .160 |
| Subarticular | 1.20 [1.08 to 1.33] | 171 [141 to 200] | −0.491 | .179 |
| Glenoid vault | 1.16 [1.05 to 1.27] | 259 [222 to 296] | 0.188 | .629 |
All data are presented as mean [95% confidence intervals]. P values are the results of Pearson’s correlation coefficients.
MRI data are presented as the ratio of osseous to muscle signal intensity, and CT data are presented in Hounsfield’s Units.
MRI, magnetic resonance imaging; CT, computed tomography; ICC, intraclass correlation coefficient.
