The primate cerebral cortex is characterized with
complicated cytoarchitecture including neurons, glial
cells, dendrites and small axons. Diffusion kurtosis
imaging (DKI) has the potential to delineate the
cortical microstructural complexity and provide
complementary microstructural information to diffusion
tensor imaging (DTI). Integrating cortical MK and FA map
from high resolution DKI and DTI could offer a
refreshing insight into the cellular microstructure
noninvasively across the cerebral cortex. In this study,
we aimed to reveal the MK and FA profile across
different cortical areas and explore the relationship of
cortical MK and FA with high resolution DKI and DTI of
macaque brains.
