Abstract


In order to demonstrate the effect of perfusion magnetic resonance (MR) and diffusion tensor magnetic resonance imaging (MRI) in evaluating glioma, arterial spin labeling (ASL) imaging is used to calculate the hemodynamic parameter cerebral blood flow. Diffusion tensor imaging (DTI) is mainly used to analyze the diffusion coefficient of water molecules in the brain, obtaining anisotropic scores, average diffusion coefficients, diffusivity parameters, etc. The separability of these parameters is studied by analyzing the distribution of single parameters, single-model multi-parameters and multi-model multi-parameters. Parameters obtained in this paper are basically consistent with those reported in the previous literature, and the statistical analysis of each parameter is also basically the same as that of predecessors.
