Length of cord edema in patients with short-interval follow-up MR imaging
Patient | Age | Time (h) | Edema Length (U) | Change in Length* | Intervening Procedure | ||
---|---|---|---|---|---|---|---|
Injury to MRI 1 | MRI 1 to MRI 2 | MRI 1 | MRI 2 | ||||
1 | 46 | 23.5 | 14 | 12 | 14 | +2 | Closed reduction |
2 | 83 | 8.25 | 40 | 12 | 16 | +4 | Closed reduction |
3 | 67 | 9.5 | 55 | 6 | 12 | +6 | Open reduction |
4 | 58 | 37.5 | 60 | 10 | 15 | +5 | None |
5 | 84 | 18.75 | 110 | 5 | 10 | +5 | Open reduction |
* Paired t test demonstrates a significant increase (t = −6.5, P = .003) in edema length. Mean change in edema length was 4.4 U (95% CI, 2.5–6.3).
