Diffusion time dependence of microstructural parameters in fixed spinal cord

TL;DR: A model of diffusion in white matter including axonal dispersion is developed and stable estimation of all model parameters from DKI in fixed pig spinal cord is demonstrated, demonstrating substantial time dependence of all parameters except volume fractions, and the additional time dimension provides support for intra‐axonal diffusivity to be larger than extra-axonaldiffusivity in spinal cord white matter, although not unambiguously.
Journal ArticleDOI

Effects of nongaussian diffusion on "isotropic diffusion" measurements: An ex-vivo microimaging and simulation study.

TL;DR: It is shown how deviations from the multiple Gaussian compartments assumption conflates orientation dispersion with ensemble variance in isotropic diffusivity arising due to intracompartmental kurtosis.
Journal ArticleDOI

Evaluation of principal component analysis image denoising on multi-exponential MRI relaxometry

TL;DR: This work evaluates the use of principal‐component‐analysis (PCA) denoising to mitigate these SNR demands and improve the precision of relaxometry measures.
