Table 2 Changes of nerve roots sedimentation in supine and prone MR images in patients with both negative and positive SedSign
From: Gravity determines the direction of nerve roots sedimentation in the lumbar spinal canal
Supine MR images | Negative SedSign (N = 25) | Positive SedSign (N = 31) |
|---|---|---|
Prone MR images | ||
Nerve roots settle to the ventral dural sac | 24 | 24 |
Nerve roots stay in the dorsal dural sac | 1 | 7 |
