Cross-subject average cortical surface maps of orientation dispersion index (ODI) and fractional anisotropy (FA). Cortical surfaces are different in terms of computation methods: original NODDI ODI (ODI_ORIG) (A,D,G), DTI-derived FA (B,E,H) and DTI-derived NODDI ODI (ODI_DTI) (C,F,I), each used different b-shell datasets: all three b-values (b_All) vs only those of b = 3000 (b₃₀₀₀) and low b-values (b₁₀₀₀), respectively. A reference cortical map of ODI (ODI_ORIG/b_All) in (A) showed high values in the early sensory areas including somatosensory, auditory, and visual. Note that ODI_ORIG/b₃₀₀₀, ODI_DTI/b_All in (C) and ODI_DTI/b₃₀₀₀ in (F) showed similar distribution to the reference. Any computation methods using b1000 (H,I,J) did not show comparable pattern with the reference. Data at https://balsa.wustl.edu/pkkKj.
