Table 3 Average tissues volumes of WM, GM and CSF (without sulcal CSF) obtained from 22 scans in the eleven subjects, before and after normalization, comparing our method with histogram matching (unit: mm3)

From: Histogram-based normalization technique on human brain magnetic resonance images from different acquisitions

  WM GM CSF (without sulcal CSF)
Volume (reference image) 468,400* ± 54,664 538,990* ± 49,667 1,260* ± 193
Volume (input image) 409,480 ± 54,011 572,560 ± 47,994 1,058 ± 187
Volume (normalized image with hist. match) 443,790 ± 56,273 547,810 ± 53,457 1,148 ± 189
Volume (normalized image with hist. normalization) 451,083* ± 53,326 540,940* ± 48,757 1,225* ± 199
  1. Data layout: mean ± std.
  2. * Statistically significantly the volumes with HN method are identical to the volumes of the reference image (p value <0.05).
