ABSTRACT
A statistical differential analysis framework of longitudinal
MRI volumes is proposed, based on difference maps af-
ter non-linear contrast midway mapping, to quantify tumor
growth. This mapping was used to normalize MRI scans to a
common range of values, and was adapted in this work to han-
dle multiplicative MRI inhomogeneity fields. This lead to two
direct applications: (1) change detection from a statistical test
on differences in midway-mapped MRI data, and (2) tumoral
growth quantification. A clinical evaluation was performed
