| 中文摘要: |
| 体素内不相干运动（IVIM）DWI是基于传统DWI的新技术，其原理是通过选取多个扩散敏感系数（b值）及采用双指数模型拟合，同时获得表征组织扩散和灌注的双重信息，可更全面地揭示疾病的病理生理改变。IVIM DWI已逐步应用于全身多个系统疾病的诊断、鉴别诊断及疗效评价。本文就IVIM DWI的原理及在椎体病变中的应用进展进行综述。 |
| 英文摘要: |
| Based on traditional DWI, intravoxel incoherent motion (IVIM) DWI can obtain the dual-messages of diffusion and perfusion of characterized tissue, with the principles of selecting multiple b-values and using bi-exponential model, therefore can reveal pathophysiological changes of disease comprehensively. IVIM DWI has been gradually applied to diagnosis, differential diagnosis and therapeutic evaluation of whole body multiple systemic diseases. The progresses of IVIM DWI and the application progresses in vertebral diseases were reviewed in this article. |
