• 3-mm DSI 203-direction data (n=90)

The diffusion images were acquired on a SIEMENS Trio scanner using a 2D EPI diffusion sequence. TE=142 ms, and TR=9100 ms. A diffusion spectrum imaging scheme was used, and a total of 203 diffusion sampling were acquired. The maximum b-value was 6000 s/mm2. The in-plane resolution was 2.9 mm. The slice thickness was 2.9 mm.

• 2-mm DSI 203-direction data (n=1)

The diffusion images were acquired on a SIEMENS Trio scanner using a 2D EPI diffusion sequence. TE=131 ms, and TR=11500 ms. A diffusion spectrum imaging scheme was used, and a total of 203 diffusion sampling were acquired. The maximum b-value was 4000 s/mm2. The in-plane resolution was 1.9 mm. The slice thickness was 1.9 mm.

• 2.5-mm DTI, HARDI, and DSI data of the same subject (n=1)(OneDrive) (Zenodo)
