Table 2 Mean values (mean ± SD) and statistical results of regional cord blood volume in tumors and the pons.
From: T2* dynamic contrast enhanced MR perfusion for cervical cord lesions; does it work?
Ratio between perfusion in tumors and perfusion of the pons | Min.–Max. | Mean ± SD | Median |
|---|---|---|---|
In low-grade tumors (n = 5) | 0.38–2 | 0.98 ± 0.62 | 0.86 |
In high-grade tumors (n = 8) | 0.41–2.5 | 1.32 ± 0.8 | 1 |
