An accurate differentiation between vestibular schwannomas (VS) and meningiomas is critical in determining treatment strategies and clinical prognoses, but misdiagnoses may occur when typical imaging appearances are absent. We prospectively assessed the performances of diffusion kurtosis imaging (DKI) and three-dimensional arterial spin labeling imaging (3D-ASL) in the differentiation of VS and meningiomas with atypical appearance. Our study showed that DKI and 3D-ASL are useful for differentiating VS and meningiomas with atypical appearance, with kurtosis values of DKI have the best diagnostic efficiency.
