  1. p: p value for F test (ANOVA) with repeated measures for comparing between different period
  2. Significance between periods was done using Post Hoc Test (adjusted Bonferroni)
  3. p1: p value for comparing between DIR and FLAIR
  4. p2: p value for comparing between DIR and T2
  5. *Statistically significant at p ≤ 0.05
