In this repository, I am sharing the code to process the radial tensor kurtosis from diffusional kurtosis estimates extracted from DIPY's diffusional kurtosis imaging data fit.
Radial Tensor Kurtosis is defined according to Hansen et al., 2017.
To see how to apply the code to diffusion MRI datasets give a look to the notebook:

As demonstrated in simulations, radial tensor kurtosis estimates are more robust to implausible negative kurtosis estimates than conventional radial kurtosis, notebook:
