The role of dendritic spines in water exchange measurements with diffusion MRI: Double Diffusion Encoding and free-waveform MRI
Arthur Chakwizira, Kadir ÅimÅek, Filip Szczepankiewicz +2
Time-dependent diffusion MRI enables the estimation of water exchange rates in vivo, yet reported values in grey matter remain inconsistent. While most studies attribute these esti…

Diffusion MRI with double diffusion encoding and variable mixing times disentangles water exchange from intrinsic kurtosis
Arthur Chakwizira, Filip Szczepankiewicz, Markus Nilsson
Double diffusion encoding (DDE) makes diffusion MRI sensitive to a wide range of microstructural features, and the acquired data can be analysed using different approaches. Correla…
