Note:—DTI indicates diffusion tensor imaging; NAWM, normal-appearing white matter; TSC, tuberous sclerosis complex; GCC, genu of corpus callosum; SCC, splenium of corpus callosum; L-EC, left external capsule; R-EC, right external capsule; ADC, apparent diffusion coefficient; FA, fractional anisotropy; L-PLIC, left posterior limb of internal capsule; R-PLIC, right posterior limb of internal capsule; L-ALIC, left anterior limb of internal capsule; R-ALIC, right anterior limb of internal capsule.
a Regions of interest were drawn in the GCC and SCC bilaterally (L and R) over the EC and in both left and right hemispheres over the ALIC and PLIC.
b The 3 eigenvalues, λ1, λ2, and λ3, and ADC are expressed in 10−6 [mm2/s].
c The FA, the relative anisotropy, and the anisotropy index are dimensionless.
