Purpose
The purpose of the study is to identify differences between axisymmetric diffusion kurtosis imaging (DKI) and standard DKI, their consequences for biophysical parameter estimates, and the protocol choice influence on parameter estimation.
Methods
Noise‐free and noisy, synthetic diffusion MRI human brain data is simulated using standard DKI for a standard and the fast “199” acquisition protocol...
Purpose
To compare the estimation accuracy of axisymmetric diffusion kurtosis imaging (DKI) and standard DKI in combination with Rician bias correction (RBC).
Methods
Axisymmetric DKI is more robust against noise‐induced variation in the measured signal than standard DKI because of its reduced parameter space. However, its susceptibility to Rician noise bias at low signal‐to‐noise ratios (SNR) is...
