Whole-Tumour Histogram Analysis of Multiple Diffusion Metrics for Meningiomas Grade

An accurate assessment of the World Health Organization grade is vital in meningiomas. While many studies have investigated the usefulness of conventional DWI and DTI for noninvasive grading intracranial meningiomas, there are neither any studies comparing three advanced diffusion model including DKI, MAP and NODDI with DTI for predicting meningioma grade. Thus, it is vital to evaluate whether these advanced models derived from diffusion spectrum imaging can also be beneficial in grading meningiomas. Our results suggested that whole tumour histogram analyses of the diffusion metrics from multiple diffusion models are promising methods in grading meningiomas.
