  1. aData are numbers of detected lesions
  2. bData are relative differences in the numbers of detected lesions expressed as percentages of lesion numbers identified with 3D-FLAIR imaging compared with the corresponding 2D-FLAIR and T2 imaging
  3. cp value was obtained from Wilcoxon analysis for matched pairs indicating that more or fewer patients showed higher lesion load measurement with 3D-FLAIR imaging in comparison with the corresponding 2D-FLAIR or T2 imaging
  4. *Significance <0 .05
