This study evaluated and compared the potential of
diffusion-weighted imaging (DWI) using mono-exponential,
bi-exponential and mono-exponential high-b values models
in the grading of gliomas. The results suggested that
multi-model DWI is useful in the grading of gliomas.
ADChigh may become a novel parameter to reflect AQP4
