Visual Assessment of T1 Signal Intensity at Standard Locations in Anorexic and Control Subjects
| Intensitya | |||
|---|---|---|---|
| Location | Anorexic (20) | Control (19) | pb |
| Distal femur metaphysis | 0.64 ± 0.18 | 1.22 ± 0.18 | .03 |
| Proximal tibia metaphysis | 0.54 ± 0.16 | 0.96 ± 0.16 | .08 |
a
Age-adjusted mean ± standard error, scale from 0 (homogeneous hyperintensity, characteristic of yellow marrow) to 4 (all dark, characteristic of red marrow). One control image was of insufficient quality to assess
b
From analysis of covariance comparing anorexic to control, adjusted for age. Corroborated by Wilcoxon test allowing for skewed data.
