Table 5.

Linear regressions between T1ρ and T2, T1ρ and age and T2 and age for the normal T2 relaxation time subset. Normal T2 relaxation time is defined to be T2 relaxation time less than the mean plus one standard deviation of the T2 relaxation time for all samples. The correlation coefficient (R²) and p-value are given.
