Average diffusion parameters in heterotopia, normal‐appearing gray and white matter

	FA	ODI	ICVF	FISO
Patient heterotopia	0.28 ± 0.09	0.34 ± 0.09	0.47 ± 0.04	0.02 ± 0.04
Patient (gray matter)	0.14 ± 0.08	0.47 ± 0.10	0.46 ± 0.13	0.20 ± 0.23
Patient (white matter)	0.32 ± 0.17	0.33 ± 0.13	0.50 ± 0.09	0.08 ± 0.12
Control (gray matter)	0.15 ± 0.11	0.46 ± 0.13	0.48 ± 0.14	0.22 ± 0.24
Control (white matter)	0.35 ± 0.19	0.32 ± 0.14	0.55 ± 0.10	0.11 ± 0.15

Average diffusion imaging parameters obtained in the patient and a healthy age‐matched control. Fractional anisotropy (FA), NODDI parameters (orientation dispersion index [ODI], neurite density approximated by intracellular volume fraction [ICVF], isotropic volume fraction most likely due to CSF [FISO]).
