Table 3 contrast measurements in patients with focal cortical dysplasia compared between DIR, FLAIR, and T2 MRI (Data are presented as means (SDs))

From: The value of double inversion recovery MRI sequence in assessment of epilepsy patients

Parameter DIR FLAIR T2 p1 p2
SNR 157 (45.8) 132 (95.7) 127 (27.5)  > 0.05  > 0.05
CR 0.32 (0.09) 0.09 (0.06) 0.11 (0.05)  < 0.05*  < 0.05*
CNR 39.5 (17.1) 14.5 (16.7) 11.9 (6.2)  < 0.05*  > 0.05
AI 27.6 (6.5) 9 (5.4) 10.1 (4.6)  < 0.05*  < 0.05*
  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
