• Table 2:
  The results are wrong due to sign errors for some of the relative differences. The correct results are:

  Size	Number of lesions	Voxel-count	Corrected
  <2ml	33	16.0 (33.5)	6.5 (19.4)
  2-10ml	62	9.2 (16.2)	4.4 (9.2)
  >10ml	37	0.8 (11.7)	0.8 (10.7)
  All	132	8.5 (21.6)	3.9 (12.9)

  Nevertheless, the conclusion given in the paper holds true.
  
  This erratum has already been corrected in the copy of the paper that is available via this website and via the SPIE Digital Library.
