| 图1 不同b值范围计算的多个扩散模型定量参数差异图，参考图为以b值0 ~2 500 s/mm2计算所得.图中每行显示不同扩散定量参数和bmax值扩散加权图像，每列显示不同b值采集方案的定量参数以及其与参考图像的残差 |
| Fig. 1 Comparisons between quantitative parameters of multiple diffusion models based on different ranges of b-values, with parameters from b-value 0~2 500 s/mm2 serving as the reference image. Each row displays different diffusion quantitative parameters and the diffusion-weighted image with the maximum b-value, while each column displays quantitative parameters from different b-value acquisition schemes and their residuals compared to the reference image |
