Current routinely used MR techniques are often insufficient in accurate grading of glioma. Hence, in most cases a biopsy is warranted in order to obtain a definitive diagnosis. In this study, we evaluate the potential role of diffusion kurtosis imaging (DKI) in the grading of gliomas. 16 patients with cerebral glioma prior to any treatment underwent DKI imaging on a 3T MR scanner. Significant difference in mean kurtosis (MK) between high and low grade glioma was demonstrated, thereby showing a better separation in comparison to parameters from conventional diffusion imaging. MK is a potential new biomarker in grading of glioma.
