Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary objectives of this study are, first, to quantify the position of the conus medullaris on prone-position MRI in asymptomatic subjects. The measurement is performed statically in a single position (prone) and serves as a surrogate parameter for potentially limited mobility. Second, the position of the filum terminale is assessed under the same conditions. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondarily, the reproducibility of the prone MRI findings is to be evaluated, and potential correlations between the collected parameters and demographic factors (age and sex) are to be investigated. | — |
