Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Comparison of the dura mater in standard MRI imaging with that in imaging performed with the upper body elevated. The comparison will be conducted quantitatively if possible; however, the primary objective is to confirm the presence or absence of visible changes. The focus is on observing changes in the images caused by the change in posture. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Measurement of the anteroposterior diameter of the lumbosacral dura mater in sagittal imaging of full-spine MRI. 2. Quantification of signal intensity changes in the lumbosacral region caused by postural variation. 3. Measurement of the angle of the dura mater tip at the terminal end of the lumbosacral dura mater. 4. Evaluation of safety. | — |
