Meningioma as an extra-axial tumor of meninges is difficult to interpret within brain interface using normal Magnetic Resonance Imaging sequence protocol. Recently, Various advancement in diffusion Magnetic Resonance Imaging (dMRI) techniques such as DTI (Diffusion Tensor Imaging), DKI (Diffusion Kurtosis Imaging) and NODDI (Neurite Orientation Dispersion and Density Imaging) has been utilized as an emerging diagnostic tool to measure the degree of mobility of water molecules within biologic tissue and investigate micro-structural integrity of the brain tissue. Thus, we aim to differentiate meningiomas from normal brain parenchyma using DTI, DKI and NODDI metrics.
