Angular Upsampling in Infant Diffusion MRI Using Neighborhood Matching in x-q Space [PDF]
Frontiers in Neuroinformatics, 2018 Diffusion MRI requires sufficient coverage of the diffusion wavevector space, also known as the q-space, to adequately capture the pattern of water diffusion in various directions and scales.

The role of diffusion MRI in neuroscience [PDF]
NMR in Biomedicine, 2017 AbstractDiffusion weighted imaging has further pushed the boundaries of neuroscience by allowing us to peer farther into the white matter microstructure of the living human brain. By doing so, it has provided answers to fundamental neuroscientific questions, launching a new field of research that had been largely inaccessible. We will briefly summarise

Noninvasive quantification of axon radii using diffusion MRI
eLife, 2020 Axon caliber plays a crucial role in determining conduction velocity and, consequently, in the timing and synchronization of neural activation. Noninvasive measurement of axon radii could have significant impact on the understanding of healthy and ...

Gibbs ringing in diffusion MRI [PDF]
Magnetic Resonance in Medicine, 2015 PurposeTo study and reduce the effect of Gibbs ringing artifact on computed diffusion parameters.MethodsWe reduce the ringing by extrapolating the k‐space of each diffusion weighted image beyond the measured part by selecting an adequate regularization term. We evaluate several regularization terms and tune the regularization parameter to find the best
