Table 2.

Various pair-wise comparisons of MR parameters between the rabbit groups, and between the disc groups. The changes (%) were defined ΔS/So, where ΔS is the difference of two compared mean signals and So is the baseline signal.

ΔT2 Δ[23Na]
Normal vs. punctured rabbit disc 8.4 16.7
Internal control vs. degenerated disc 15.6 22.9
Normal vs. degenerated disc 18.6 30.6
Normal vs. internal control disc 3.5 10.0
