Analysis of morphologic characteristics of bony cervical spine structuresa
| Assessment, Localization | Score | Criteria |
|---|---|---|
| Cortex | ||
| Vertebral body (sag/ax) | 0 | Not visible |
| 1 | Visible, but not analyzable | |
| 2 | Clearly visible | |
| Facet joint (sag) | 0 | Not visible |
| 1 | Visible, but not analyzable | |
| 2 | Clearly visible | |
| Trabeculae | ||
| Vertebral body (sag) | 0 | Not visible |
| 1 | Clearly visible | |
| Integrity | ||
| Anterior vertebral body line (sag) | 0 | Not visible |
| 1 | Clearly visible | |
| Posterior vertebral body line (sag) | 0 | Not visible |
| 1 | Clearly visible | |
| Alignment | ||
| Vertebral body (sag) | 0 | Not visible |
| 1 | Clearly visible | |
| Facet joint (sag) | 0 | Not visible |
| 1 | Clearly visible | |
| Maximal sum | 9 |
Note:—sag indicates sagittal reformations; ax, axial reformations.

Cortex, trabeculae, and integrity were assessed on each cervical vertebral segment (eg, C3); alignment was assessed on each cervical level (eg, C3–4). The least visible cortices of each vertebral body and facet joint were used for this analysis.
