Datasets

MGH Connectome Diffusion Microstructure Dataset (CDMD) [Paper] [Download]

• Hardware: MGH-USC 3T Connectome scanner equipped with 300 mT/m maximum gradient strength, custom-built 64-channel head coil

• Participant: 26 healthy participants, 7 out of 26 participants rescanned in the same day

• Diffusion MRI Protocol: pulsed gradient spin echo sequence, 2 mm isotropic, two diffusion times (19 and 49 ms), 8 ms gradient duration, 8 gradient strengths linearly spaced between 30 mT/m and 290 mT/m per diffusion time (i.e., 8 shells), 32 (b <= 3000 s/mm^2) or 64 (b > 3000 s/mm^2) uniform directions per shell, 850 image volumes in total,  1 hour scan time, real-valued diffusion data available for 14 out of 26 participants (including all 7 participants with rescan data)

• Anatomical MRI Protocol: T1-weighted MPRAGE sequence, 1 mm isotropic (FreeSurfer reconstruction results available)
