Preoperative differentiation between high-grade
astrocytomas (HGA) and solitary brain metastasis (SBM)
may contribute to more appropriate treatment plans.
Diffusion kurtosis imaging (DKI) is the extension of
diffusion tensor imaging (DTI), which is an MRI
technique depicting the non-Gaussian water molecule
diffusion 1. DKI can be of particular interest for
noninvasively differentiating HGA from SBM.
