Low SNR is a critical issue in diffusion kurtosis imaging because of the use of high b-values (up to 3000 s mm-2). We tested different noise correction methods prior to kurtosis fitting and show that noise correction is a necessary step in kurtosis processing, providing higher tissue contrast and better parameter estimates.
