Concordance in each MR imaging sequence between 2 neuroradiologists
| Segment of the Trochlear Nerve | κ Coefficient | ||
|---|---|---|---|
| HR-MRC | BS-MRC | HR-MSDE | |
| Perimesencephalic | 0.286 | 0.643 | −* |
| Tentorial | 0.219 | 0.659 | 0.643 |
↵* The κ coefficient could not be calculated because both neuroradiologists evaluated the trochlear nerve as “visible” in all cases.
