The Role of Dendritic Spines in Water Exchange Measurements With Diffusion MRI: Time‐Dependent Single Diffusion Encoding MRI

Kadir Şimşek, Arthur Chakwizira, Markus Nilsson, Marco Palombo

Short summary

Water diffusion within dendritic spines can create time-dependent diffusion MRI signals that are indistinguishable from membrane permeability, leading to overestimations of membrane permeability by up to 60% if not accounted for.
