Simulation Study of Kurtosis Measurements in MR Diffusion Kurtosis Imaging

, 2008
Monte Carlo simulation was performed in 1D space to study the spin diffusion, kurtosis characteristics, spin dephasing and MR signal attenuation in compartment-restricted diffusion environment. The apparent kurtosis was computed based on DKI formulation

Diffusion kurtosis imaging to detect amyloidosis in an APP/PS1 mouse model for Alzheimer's disease

, 2013
: Purpose Amyloid deposition in the brain is considered an initial event in the progression of Alzheimer's disease. We hypothesized that the presence of amyloid plaques in the brain of APP/presenilin 1 mice leads to higher diffusion kurtosis measures due

Non-rigid coregistration of diffusion kurtosis data

, 2010
: Diffusion kurtosis imaging (DKI) is a relatively new model to study the non-Gaussian behavior of water diffusion in the brain white matter which introduces, besides the conventional diffusion tensor, a 4th order, 3D diffusion kurtosis tensor to ...
