Dozens of diffusion models have been created to describe the non-Gaussian nature of diffusion. Nevertheless, many of them imply assumptions that have not been rigorously confirmed, or includes abstract parameters. The purpose of this study was to observe the characteristics of varying diffusion curvature (VDC) indicators in several types of brain tumor. D0 and D1 distribution were obtained for each subject. This study illustrates the potential of applying a simple and pure empirical non-Gaussian diffusion model VDC on brain tumor imaging.
