Localization-driven exchange contrast in diffusion exchange spectroscopy
Teddy X Cai, Nathan H Williamson, Peter J Basser
Diffusion exchange spectroscopy (DEXSY) is a method to probe exchange between domains of varying confinement. Analyses of DEXSY signals typically assume Gaussian diffusion within d…

Analytical phase kurtosis of the constant gradient spin echo
Teddy X Cai, Nathan H Williamson, Peter J Basser
The Gaussian phase approximation (GPA) underlies many standard diffusion magnetic resonance (MR) signal models, yet its validity is rarely scrutinized. Here, we assess the validity…
