Diffusion Weighted Images datasets are acquired at a low
spatial resolution due to decreased SNR and increased
acquisition time as the voxel size is reduced. Achieving
high spatial resolution improves the specificity of
reconstructed tracts and diffusion features, which might
not be present at a lower spatial resolution. We show
that high resolution DWIs are achievable thanks to
proper denoising and favorably compare to the HCP
dataset, while still being feasible in 13 minutes on a
standard 3T clinical scanner. This could reveal new
anatomical details, which are not achievable at the
spatial resolution currently used in diffusion MRI.
