2026-09-21 Diff5T: Benchmarking human brain diffusion MRI with an extensive 5.0 Tesla k-space and spatial dataset doi:10.57760/sciencedb.25122 en Diffusion MRI (dMRI) has become a cornerstone technique for investigating the microstructural and connectional organization of the human brain.Diff5T is the first openly available dMRI dataset acquired on a 5.0 Tesla MRI scanner, bridging the gap between previous studies and large-scale neuroimaging projects. The dataset includes both raw k-space data and reconstructed diffusion images obtained using diverse imaging protocols. With multiple b-values and gradient directions, Diff5T offers unprecedented flexibility for studying brain microstructure and connectivity. In addition, high-resolution T1-weighted (T1w) and T2-weighted (T2w) images are provided to support detailed structural and anatomical analyses.Notice:All publications using these data must cite the original Diff5T publication:“Wang, S., Yu, S., Cheng, J. et al. Diff5T: Benchmarking human brain diffusion MRI with an extensive 5.0 Tesla k-space and spatial dataset. Scientific Data 12, 1352 (2025). doi:10.1038/s41597-025-05640-2.”Failure to provide the required citation constitutes a violation of this Agreement and must be remedied through an appropriate correction to the publication.
