Mean diffusivity (unit: 10⁻³ mm²/s) comparison between in vivo and ex vivo scans for PND5 and PND14 scans.

	PND5 (in vivo)	PND5 (ex vivo)	PND14 (in vivo)	PND14 (ex vivo)
GCC	0.970 ± 0.053*	0.284 ± 0.022	0.734 ± 0.047*	0.233 ± 0.018
BCC	1.120 ± 0.089*	0.394 ± 0.047	0.884 ± 0.086*	0.344 ± 0.031
SCC	0.930 ± 0.055*	0.293 ± 0.026	0.865 ± 0.045*	0.277 ± 0.028

Significant differences were found in MD between the in vivo and the ex vivo scans (*P < 0.05).
