MRI parameters for the thoracolumbar spine.
| Parameter | Description |
|---|---|
| Superior extent | Vertex of T11 (one slice above T11). Bony detail should bevisible from T-11 |
| Inferior extent | Infracoccygeal (one slice below the tip of the coccyx) |
| Sequences | Scout |
| Sagittal T1-weighted image (T1WI) | |
| Sagittal T2-weighted image (T2WI) | |
| Axial T1-weighted image (T1WI) | |
| Axial T2-weighted image (T2WI) | |
| Axial T2 gradient echo | |
| Plane | Sagittal and axial |
| Slice thickness | 3 mm |
| Interslice gap (spacing) | 0 mm |
| Matrix | 256 × 256 highly recommended |
| FOV | 20–25 cm required |
| NEX | 1–2 |
| Number of slices | Follow up timepoint must be consistent with screening. |
