Image processing workflow. Anatomical images were used to manually segment FCD, leading to binary label generation. The FA, MD, RD, and AD maps were derived from DTI raw data; subsequently, b0 were separated from b1000 images. A mean b1000 volume was created and co-registered to the anatomical images. The coregistration matrix derived from the previous step allowed the alignment of the anatomical images, the binary label, and the above maps. The average FA, MD, AD, and RD values within the binary label were calculated, and then the label was flipped to the contralateral side to evaluate the CBP. FCD: Focal cortical dysplasia, CBP: Contralateral brain parenchyma, FA: Fractional anisotropy, MD: Mean diffusivity, AD: Axial diffusivity, RD: Radial diffusivity
