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 ponsMin.–Max.Mean ± SDMedian
In low-grade tumors (n = 5)0.38–20.98 ± 0.620.86
In high-grade tumors (n = 8)0.41–2.51.32 ± 0.81
  1. Z value for Mann Whitney test, 0.456; p value, 0.322 Statistically significant at p ≤ 0.05
