Table 2 Number of detected lesions in all patients in different brain regions by each used sequence and relative comparison of 3D-FLAIR versus 2D-FLAIR and T2 pulse sequences

From: Diagnostic value of 3D-FLAIR magnetic resonance sequence in detection of white matter brain lesions in multiple sclerosis

Regions   Relative comparison (%)b
3D-FLAIRa 2D-FLAIRa T2a 3D-FLAIR/2D-FLAIR P value c 3D-FLAIR/T2 P value c
Supra-tentorial Periventricular 107 83 76 29 0.001* 41 0.001*

  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
