Table 3. Inter- rater reliability.
Interrater reliability for each imaging modality in the axial and sagittal projections. Krippendorff’s alpha coefficient range from 0 (perfect disagreement) to 1 (perfect agreement).
| Sagittal projection | Krippendorff’s alpha |
|---|---|
| CTM | 0.63 |
| MRI T1 | 0.66 |
| MRI T2 | 0.59 |
| Axial projection | Krippendorff’s alpha |
| CT | 0.67 |
| MRI T1 | 0.56 |
| MRI T2 | 0.57 |
