An accurate evaluation of the WHO grade and cellular proliferation is particularly important in meningiomas, it may facilitate treatment decisions and improve clinical prognosis. But conventional magnetic resonance (MR) imaging were not sufficiently accurate in evaluating the meningioma grade and Ki-67 expression. This study prospectively evaluate and compare diffusion kurtosis imaging (DKI), diffusion tensor imaging(DTI) and diffusion weighted imaging (DWI) metrics in determining the grade and cellular proliferation of meningiomas. It was found that DKI is a better diffusion technique for assessing the grading and cellular proliferation of meningiomas compared to conventional diffusion imaging.
