Two representative cases. The delineation of the volume of interest (VOI) is shown by the red lines on the b0 images. (A) 43-year-old female patient presents with NMDA-IgG positivity autoimmune encephalitis. (B) A 52-year-old male patient with left temporal glioblastoma (World Health Organization grade 4). T1CE, T1 weighted contrast enhancement; DKI, diffusion-kurtosis imaging; MK, mean kurtosis; DTI, diffusion-tensor imaging; MD, mean diffusivity; FA, fractional anisotropy; MAP, mean apparent propagator; MSD, Mean squared diffusion; NG, mean non-Gaussianity; RTOP, return-to-origin probability; QIV, q-space inverse variance; NODDI, neurite orientation dispersion and density imaging; ICVF, intracellular volume fraction; ODI, orientation dispersion index.
