Fig. 4From: Inter-site harmonization based on dual generative adversarial networks for diffusion tensor imaging: application to neonatal white matter developmentInter-site differences in fractional anisotropy (FA) values before and after harmonization using different methods. Red represents that site 2 holds significantly (P < 0.05) higher FA than site 1. Blue represents that site 2 holds significantly (P < 0.05) lower FA than site 1. Green represents regions without significant difference between two sites. Note: dual generative adversarial networks are performed with the 2-dimensional kernel on axial slices. For inter-site comparisons after harmonization, differences with P < 0.05 in any run of the sixfold cross-validation are overlaid together on the template mapBack to article page
