This paper estimates axon conduction velocity in vivo from MRI parameters, showing that 89.2% of variance is explained by axon diameter and g-ratio, with accurate estimates achievable under certain parameter bounds.

This paper introduces a method to quantify uncertainty in diffusion MRI models, showing it improves artifact detection and statistical power in group studies.

The paper evaluates MCMC algorithms for diffusion MRI microstructure models, finding that Adaptive Metropolis-Within-Gibbs with MLE initialization provides fast and robust sampling.
