| Phase | Magnitude | Combined | |
|---|---|---|---|
| Mean score visibility | 3.47 | 0.99 | 2.03 |
| Mean score delimitation | 2.08 | 0.28 | 1.35 |
| No. cases with score 4 or 5 for visibility | 44 | 2 | 9 |
| No. cases with score 4 or 5 for delimitation | 10 | 0 | 1 |

Note:—STN indicates subthalamic nuclei; SENSE, sensitivity encoding.
